January 7th – January 14th (4 hours) –  Last week I went back to my internship site, and started working on a few different things. In order to make our Wikipedia page we need to find the links to other Wiki pages that already exist. I started going through Wikipedia pages that already exist, such as “two-photon microscopy” and “fluorescent microscopy.” I was looking for ways they connect to multiphoton microscopy, so I could find where to put them in our page. I also was looking for things that someone else already explained, such as mode-locking, so we wouldn’t end up explaining it again. Then my mentor and I started thinking about our schedule and after I got the dates from the Vail District Office meeting I sent them all to my mentor.

One skill I’ve learned from my internship is how to run the computer program for the multiphoton microscope. The computer tells the microscope how to move the stage so the sample goes in and out of focus. I developed the ability to run the computer program by writing down all the of the different tasks it can do and how to do them. Then I had a lot of practice taking pictures of different samples. After taking the pictures I use another program to develop them, and edit them so the second and third harmonics are visually separate from each other. I also had to practice using this program.

These programs are very similar to other scientific programs that are used at the University of Arizona and a lot of companies. Most of the equipment is the same, and the terms for the programs are common for science, which I want to go into. It will help me when I go to the University of Arizona because I will already have a basic understanding of how to run the equipment. I also will already have notes on the programs that I can always refer back to later. It will help me with my career because companies that need science-related fields mostly use the same program. It also helped me figure out how to create my own cheat sheet that I can recreate for other programs I might need to use later.

One thing I always have to be careful of when I develop the pictures is photo-bleaching. Photo-bleaching is what happens when a photo is overexposed and some of the detail is lost. It’s very easy to photo-bleach on the program I use because it some parts of a picture require a lot of exposure to see the details while other pieces only need a little. This is why I have to be careful of the details I can lose.

January 15th – January 28th (10.5 hours) – Over the last couple weeks I’ve spent a lot of time on the Multiphoton Wikipedia page. I finally finished collecting other pages we can link to, and I’ve started working on the introduction to our page. We’ve decided to start off with a definition of Multiphoton Microscopy, then add some of the history behind it, and what makes it so useful. I also helped make a diagram that might be used in the Multiphoton Microscope Manual on a raster pattern. A raster pattern is the specific way the microscope’s laser scans over a sample. It starts at the top corner, scans across, moves down a line, and repeats this process over the sample. Then on Martin Luther King Day I got a little more practice with splicing. I cleaned my own piece of fiber and watched how two fibers are spliced together for one of Ben’s microscope projects.

I didn’t learn many new terms this reflection log, but I did learn a lot about the history of the Multiphoton. One person I fond very interesting was Maria Goeppert Mayer. She was a German mathematician and physicist, who theorized the impact of two-photon microscopy as a graduate student at the University of Göttingen. She also had a very small part in building the atomic bomb in the Manhatten project, but after seeing how much destruction it led to she’s happy it was only a small part. She got the Nobel prize in physics on her proposal of the nuclear shell model of atoms.

January 29th – February 11th (8.5 hours) – Over the last few weeks I’ve been continuing my work on the Multiphoton Microscopy page, and I’ve done a lot of research on gemstones. I’ve learned about what differentiates gemstones and where they come from. Pearls are an oyster’s immune system reacting to the presence of a foreign body. Also, emeralds are more rare than diamonds, but diamonds cost more because diamond distributors keep a stash of them to keep the prices high. Sapphires and rubies are from the same crystal, but rubies are red because they have an inclusion of chromium. Clear sapphires have been used in place of diamonds in jewelry by sellers because they look so similar. And aquamarine was once believed to help sailors have a safe journey and cure laziness.

One of my SMART goals was to compile a list of Wikipedia resource pages to include in our Multiphoton Wikipedia page. I’ve been working on this goal for the last month, and I have an extensive list of links that will be added to our page once it’s finished. We chose this to be one of my goals because Wikipedia pages all have links to other pages in case the reader wants further information. Within the text, Wikipedia has links to other pages on the site, but at the bottom of each page there is a works cited that anyone can go to for information outside of Wikipedia. Therefore, we needed to have a list to the links we knew Wikipedia had and ones we knew would have to be listed at the bottom of our page. I started working on this goal by creating a list with my mentor of the things we want to talk about in our page. We decided to discuss the history, physics, and uses of Multiphoton Microscopy, so I started looking into pages about nonlinear optics. Multiphoton Microscopy is a type of nonlinear optics that helps create more detailed images of a sample than other microscopes. It’s able to not only scan the surface of a material, but most times it can also go inside to a significant depth. I had to find all of the pieces that go into Multiphoton Microscopy, such as the laser, mirrors, filters, and wavelengths that it’s typically used on. After a couple weeks I was able to come up with a list of resources that were solely for how the Multiphoton Microscope works. Then I moved onto the history of Multiphoton Microscopy. This was the difficult part because there isn’t much history. The field of optics is very new, compared to other science fields, so we’re often the first ones trying new things with the microscope. Wikipedia has nothing on the first Multiphoton Microscope because it wasn’t built until 1990 by Winfried Denk, Watt W. Webb, and Jim Strickler; even though it was first theorized by Maria Goeppert Mayer in 1927. Multiphoton Microscopy has only been around for thirty years, so there hasn’t been a lot of history made with it yet. However, I’ve recently started looking more into the uses of Multiphoton Microscopy, which is much more interesting. Due to how young this technology is, the limits are almost unknown. My mentor has been trying new sampled under the microscope to gain an understanding of how it can be used. One of the projects he’s working on will help doctors find pancreas cancer in a patient sooner, and be able to get rid of it more efficiently. He’s begun working with a team from the Biomedical College to create bubbles that will attach to cancerous cells and glow under the microscope. Then a doctor, in theory, would be able to inject their patient with these bubbles, look at parts of their pancreas under the Multiphoton Microscope, and determine more accurately if and where the patient has cancerous cells. Because many of the uses will come from our lab, the page will most likely have links to the research being done in the University of Arizona’s Nonlinear Fiber Optics group. Compiling a list like this will help in my future because I am going into Materials Science Engineering, which requires that I have the ability to write a paper similar to this one. I’m also learning a lot of research techniques that will benefit the quality of my sources in the future.

February 12th – February 25th (8 hours) –  Over the last couple weeks I’ve spent a lot of time writing the Wikipedia page. So far I’ve written about the Multiphoton’s history, applications/advantages, and recently the commercial Multiphotons that already exist. I did a lot of research on the companies: Ziess, Thorlabs, Nikon, and Leica because each one has at least one model of the Multiphoton Microscope. I also started looking into the different labs that use Multiphoton Microscopy around the world. There are a few in some Midwestern states and in London that are working on biomedical uses, so we’re the only lab that’s really used the Multiphoton on other things like gemstones. We’ve imaged pearls, rubies, sapphires, emeralds, tourmaline, alexandrite, and a diamond. I plan to use some of these images in my SEP presentation.

While researching gemstones I’ve learned a lot about the difference between inclusions and imperfections. Imperfections can be reduced using heat treatment, but usually inclusions come to the surface when a gem is heat treated. The inclusions are what tells geologists where a certain gemstone is from.

February 26th – March 11th (7 hours) – Over the last few weeks I haven’t gone in to my internship site as much because my mentor was out of town for a few days over his spring break. When I was there I helped move the Multiphoton Microscope over to the other lab Dr. Kieu has in order to test a 1300nm laser they’re building. However, I wasn’t able to help them test the laser because they didn’t have enough safety goggles for me to be in the room with such a dangerous laser. So I wrote a lot about the theory behind Multiphoton Microscopy and how we run the laser using a system called LabView. Then I created my own Wikipedia account so I could start putting my words on a page that’s in the correct format. I learned a lot about how Wikipedia maintains pages that look similar because of a specific coding language for Wikipedia alone. Since I took Computer Science my sophomore year it wasn’t too difficult to figure out, and now we have a page that looks like an official Wikipedia page. Next is some revising and adding my figures to each section to make it more visually appealing.

For my second SMART Goal my mentor and I decided I should create my own diagram of the Multiphoton Microscope for our Wikipedia page. The reason we chose this goal is because our page will need images that go along with the information, and we can’t use already published diagrams made by our group. My mentor also wanted to help me understand a little more about the Multiphoton Microscope design. I started to work on completing this goal by learning about the tool I would be using, called Photoshop CC. This tool is often used by professionals when creating their own diagrams and my mentor is very familiar with it. I spent one afternoon going through all of the tutorials and getting the hang of using it. I can only work on it at my site because I don’t have this tool at home, so this project took longer than my first SMART Goal. I used one of my mentor’s diagrams and another one by Warren R. Zipfel, who published a paper on Multiphoton Microscopy a few years ago called “Nonlinear Magic: Multiphoton Microscopy in the biosciences.” I studied these diagrams and decided on the best way to make my own. I started with the basic elements I understood and then I had to ask for my mentor’s help on some of the physics I didn’t understand. At the beginning of my diagram I have a fiber laser that is shooting out a beam. This beam is then rerouted with scanning mirrors that can be adjusted to create the raster scan we use over our sample. A raster scan basically has the laser beam start in one of the top corners, scan across the sample, move down one micrometer, and scan across again. After the beam is redirected by the scanning mirrors it goes through a scanning lens and tube lens to help refocus the beam through the objective. The objective is a piece that has multiple lenses inside to focus the beam at a certain angle. Where the beam is focused is how far away our sample should be to get the best resolution. The beam interacts with the sample before it’s shot back through the objective to two dichroic filters. These filter out the Second Harmonic and Third Harmonic wavelengths that are then sent to highly sensitive detectors. Once picked up by the detectors, the information can go to the computer for us to view and process later. My diagram is a very basic outline of how to Multiphoton Microscope works, and it doesn’t represent every Multiphoton Microscope out there. The reason it’s so basic is we needed a diagram that we could add to Wikipedia. For our page to be useful the most basic outline has to be used. The biggest hurdle I had while creating this picture was understanding the tube lens. I wasn’t sure what happened to the beam in that area, so I had to ask my mentor a little bit about the physics in that area. The main characters in completing my goal are my mentor and Warren R. Zipfel. Warren R. Zipfel is an Associate Professor at Meinig School of Biomedical Engineering, and he specializes in the development and application of optical microscopy for biomedical research and for clinical imaging applications. This will be a very helpful in creating the Wikipedia page on Multiphoton Microscopy and it’ll help me with any future diagrams I might make. Going into Science will most likely mean that I have to create my own diagrams for projects I’m working on and learning how to use this program now will make it easier in the future.

March 12th – March 25th (21 hours) –  Over the last couple weeks I’ve spent a lot of time at my internship site because of fall break. A lot of it went toward the Wikipedia page, and making my diagram. I finished my diagram the first week, and added all of my pictures to the page the second week. I also had Ben review my writing, so he could add any details he thought we should tell people about. After a little bit more editing we plan on sending it to Dr. Kieu for further review before publishing it. I spent more of my time coding for the Wikipedia page because I already had many of the sections typed up, but not in the correct format. I learned the code for images and sections, so now it looks like an official Wikipedia page. I also finished taking pictures of gemstones, and I had the opportunity to look at some pancreatic cancer cells. One of the med students from the Biomedical college brought over alive cells with pancreatic cancer and we looked at them under the microscope. We weren’t able to find any of the bubbles that are supposed to attach to the cancerous cells, but it was still an amazing experience.

This last week a learned a little bit about a tool in optics called an isolator. Isolators are switching devices that make sure the laser beam going through a piece of fiber is only directed one way. Without an isolator the beam could end up going the opposite way intended. I learned this from another one of my mentor’s projects where he’s building a 1 micron laser.

March 26th – April 8th (6.25 hours) –  Over last couple weeks I spent a lot of time finishing projects. Because Ben will be out of town for a lot of April, we earned a lot of hours over the break and I got a lot of work done. I’ve finished writing the Wikipedia page, and hopefully Dr. Kieu will get back to me with anything he would like to add so I can publish it. I also gave a practice SEP presentation to a few people Ben asked to come see it. They said I did very well and gave me a few tips on how to make it better. The main ones were to not move my feet as much while I talk, and to change some of the formatting on my slides. I’ve since then edited my slides, and I will keep in mind Ben’s tip to stand still at my second practice and real presentations. I also was lucky enough to meet with the Senior Academic Counselor in the Optical College to talk about optics as a college major. I learned that there are actually more than one track to the optical engineering program, and I’m really interested in the Opto-Materials degree. It would be a degree that can combine my interests in both materials science and optics. It’s a good thing the University of Arizona doesn’t allow students of engineering to declare the type of engineering they want until their sophomore years because I will need a little bit more time to fully decide. However, Opto-Materials is looking the best right now.

I’ve found that I can learn a lot of technical skills pretty quickly. I was able to start running the Multiphoton Microscope all by myself after only a few days, and I’ve worked with new computer programs, such as Photoshop. It helps that I took notes on the basics, and I was able to look up how to program a Wikipedia page. However, I did find that I’m hesitant to ask questions. At the beginning of the year there was so much information that I didn’t feel like asking about every single detail, but I probably should have. It would’ve helped my understanding later on, and I tried to ask more questions this last semester. Ben commented that he’s seen improvement in that area, so I plan on continuing my improvement as I go to college.

I would recommend they keep multiple calendars that they can check throughout the day. I have two calendars for different things because if I only kept one it’d be impossible to read. I kept one with upcoming assignment dates, and the other was for bigger events. Both were easily accessible with my phone, so I could check both within minutes. I also recommend being ahead of each assignment because it is sometimes very difficult to fit two schedules together. Sometimes I had to wait for a response from someone else, so they should give themselves time on assignments that require waiting on someone else.


I think the biggest thing I’ve learned is the Opto-Materials degree. At the University of Arizona they offer it through the College of Optical Sciences, and it’s an optical science degree, but it includes materials science courses. For my technical classes I can take materials science classes and minor in materials science engineering. This degree is one that I plan on looking further into.

April 9th – April 22nd (0 hours) – My experience in the internship program has been amazing. I’ve learned a lot of things I wouldn’t have learned doing the normal Senior Exit Project the Vail School District requires of all seniors. Through courses like the Resumé Building Class and my Professional Development Meetings I’ve learned a lot of techniques that help make professionals. I’ve learned how to answer questions in an interview, and I’ve even gained some experience being an interviewer for next year’s interns. I had an amazing time working with my mentor, while learning a lot about my future college. I plan on going to the University of Arizona, so working in their College of Optical Sciences has helped me become familiar with the campus, how research groups work, and what my classes will most likely be like. I’m very excited to go into engineering, and this opportunity has opened my eyes to Opto-Material Science, which I’m likely going to pursue in college.

July 20th – August 13th (4.13 hours) – I started my internship by going on a tour, given by Dr. Kieu, of the current projects his students are working on. He showed me the lab they build laser in, along with a lab that was actually putting a multiphoton microscope into use. I am working with the students using the multiphoton microscope on collecting data from things such as geographical samples and cancer cells. I spent most of my first few days filling out University of Arizona paperwork that will allow me to actually use the microscope, as well as the internship paperwork. My mentor and I have figured out a schedule that works for us where I go in once a week on Wednesday to fit with his busy schedule. So far I have had the opportunity to look at different samples from things such as fresh fish gills to dog tongue under a light microscope, and I’ve started making observations in my very own scientific journal. I was not able to use the multiphoton microscope yet due to a big project they’ve been working on for years using it for the entire time I was there. It is a very exciting paper on finding pancreatic cancer tissue in a more efficient way using a laser, and I can’t wait to see if they are able to get any further with their recent discoveries from a fresh mouse pancreas that only lives for 48 hours after it has been removed from the mouse.

I hope to learn certain skills that will help me in my future career. I would like to work on my people skills especially because I already feel I am a very organized person, but sometimes I struggle in communication. I feel that working in a research-based environment will help, not only improve my organization skills, but also teach me some technical writing. Technical writing is very unique to the scientific world, and it is often overlooked, but I understand how important it is to be able to write clearly and concisely. From my mentor, I would like to learn the physics behind lasers when using them in a microscope, as well as the ability to use a multiphoton microscope on my own collected samples. First I need to take a laser safety course, but after that I will be able to collect my own samples and hopefully get some really cool pictures of the second and third harmonic generations of microscopy.

As a student, I found it very easy to contact my teachers at a convenient time, but as a professional, I’ve discovered my schedule must be flexible in order to fit other people’s schedules. I have learned how to contact someone in an appropriate manner, and how to respond to someone in a timely and appropriate fashion. I have also learned how much effort goes into each resumé, and how much of it actually is read by a possible employer, which shocks me quite a bit. However, I have learned how to reuse things such as my resumé for new opportunities, as long as it is not out of date. One last thing I have discovered that is specific to the science field is the difference between how science is done and how science is taught. I’ve found that in most science classrooms the teacher gives the students all of the answers to what they should be looking for, but ever since my internship has started I’ve learned about how scientists observe and guess, but never really find a true answer unless they find evidence proving it true.

August 14th – August 27th (6.15 hours) – At my internship site I had a very meaningful experience when I visited another optics lab with my mentor. My mentor started as an undergraduate student in this lab, which designs holographic technology using the light cones in things such as computer or television screens. I met the person running the lab and he talked to me about what they want to accomplish within the next year or two. They have two major goals: creating 3D movies/computers without the need for 3D glasses and create a 3D car dashboard that can be displayed up on the windshield whenever the driver of the car wants. He showed me the current lasers they are working with in order to create a 3D image, but they mostly work with the light cones in screens. In each screen is an insane number of light cones that we see from one angle, but a 3D image would mean we would need to be able to see these cones from multiple angles at one time to trick our eyes into thinking it is a 3D image. I see many advantages from these projects and it has made me more interested in the different types of optics I can learn from.

August 28th – September 10th (7.13 hours) – These last two weeks I’ve spent more time using the Multiphoton Microscope. I was able to collect pictures of samples from a meteorite that landed in Russia approximately three years ago. They pictures were very interesting, and my mentor sent them to me after they were processed so I can put them into my SEP presentation at the end of the years. I also was able to complete my interview with my mentor, and I managed to come up with a critical issue to write my SEP paper on. I plan on writing about how the scientific method isn’t appropriate to teach in schools because it doesn’t represent how scientists actually figure things out, and it scares many people away from the scientific field. This last week my mentor’s brother ran over his phone and donated it to science. That means when I went in on Wednesday I got to take the phone apart and study different pieces of it under the Multiphoton Microscope. I wasn’t able to find any conclusive data, but sometimes that happens in the scientific world. I hope next week I can collect some more pictures for my presentation!

Due to my internship location being a college, there is no specific way to conduct myself that I’ve been given. However, I spend a lot of my time listening to how different Optical applications work, and collecting pictures of different samples under the microscope. I have learned how to run the microscope, and the different rules in place that will keep it from being damaged. I also have learned some skills in technical writing through reading some articles my mentor provides me that he or other people have written about what we’re working on. It seems that in the Optics department the most appropriate behavior to have is a willingness to learn new things from other people or explore new ideas.

I, personally, believe the need for the ability to ask questions is quite suiting to my current personality. In a lot of science projects, the scientists running them don’t actually know what to expect. Of course they are able to create educated inferences based on previous testing, but a lot of people in science have a goal of being published, which means they have to run experiments that haven’t been done before. The Optics department is also very new and many different things haven’t been done because of this, so every time I go to my site I have to be willing to adapt to new projects or old ones that were never finished. I have to constantly be on the lookout for new breakthroughs, no matter how small they seem at the time. On thing I have struggled in is the level of education required to understand how the microscope works, thoroughly. I lack some of the physics and math classes that everyone else on the projects have, so sometimes I find it difficult to keep up, but that is something that I feel will change overtime.

One vocabulary term that is used a lot is “photon.” A light photon is a particle of electromagnetic energy that is very stable in comparison to other elementary particles. Photons of light often vibrate at frequencies that we can manipulate and use in the microscope to pick up on small things our eyes can’t.

September 11th – September 24th (3.25 hours) – In the last two weeks I was only able to visit my internship only once due to a few scheduling problems, but when I was there I spent most of my time learning how to research for a college paper. My mentor is writing a paper on the fluorescence of different human body parts under the Multiphoton Microscope, so we are currently in the research portion of the experiment. He provided me with a few websites to search through while he looked through others. I found a few very interesting articles on the chemical that makes jellyfish glow: aequorin. I then started researching if there were any experiments that used this chemical and found some that injected aequorin into mice with calcium. The scientists found that this allows them to track the growth of tumors in mice, which would most likely have the same affect in humans. I also was able to watch my mentor solder some wires to a diode that will eventually be put into another Microscope that I’m going to help make over Fall Break.

This week I learned the word diode at my internship site. A diode is a small piece of metal that connects wires to a light inside a small box, creating a powerful laser beam. The diodes help transfer the electricity from the wires to the light that will shoot a small piece of fiberglass wire, creating a laser powerful enough to burn the cornea in the human eye.

September 25th – October 8th (28.5 hours) – In the last two weeks I spent a lot of time at my internship. The first week I was able to tour a few other microscopy labs across the University of Arizona campus, which my mentor’s father runs. He showed me the different types of lasers the U of A uses on a daily basis and some of the projects he’s working on. I also worked with my mentor by doing some research on the different advantages and disadvantages of each of the lasers that I saw on the tour. During the second week I went to a few meetings about a project my mentor is working on to stop Pancreatic Cancer from being so deadly. They currently are testing how the bubbles that target cancer cells react with dead cancer cells in the body. Then I toured some Biomedical labs, and I was able to get the contact information from one of the well-known scientists running the Biomedical labs. He offered me a position in one of his labs when I start attending the U of A next year, and I think I might take it. Overall, these last two weeks have been very productive and I’m excited to start attending the laser classes my mentor has set up for me these next couple of weeks.

The most common use of communication at my site would be email. My mentor isn’t currently taking any classes at the U of A because he’s already gained all of the credits required to obtain a PhD, and he’s very busy working on various projects for the U of A that will allow him to write the required number of papers for his PhD. Due to his ability to stay in his lab all day long he spends a lot of time on his computer, and he sends and responds to every email almost immediately. It’s very appropriate for the U of A because the campus is rather big, and having in-person conversations would slow down some of the breakthroughs. However, in-person communication is also a big method of communication because there are multiple people in the lab I intern at. The different scientists and students often like to bounce ideas off of each other, while they work on new projects. I do have my mentor’s cell phone number in case of emergencies, but I’ve never had to use it.

I’m very comfortable using email because I have been using email to communicate with my teachers for a few years now. I also have been emailed from various colleges and other organizations, so I keep my email on my phone as well as my computer. I’m notified every time I get a new email in either my personal or business email. I also prefer email over text because I’m not the most tech-savvy person, even though I’m expected to be due to my age. I prefer to write out everything I say, and often times emails are more proper in that way. I also find that email is much easier to organize that texting, especially when I know I’ll get a very quick response from my mentor.

One vocabulary word that I’ve learned this week that isn’t exactly specific to Optics, but it’s very specific to one of my mentor’s projects. The term “ligand” is often thrown around our lab because of the Pancreatic Cancer project. The bubbles that are able to find the cancerous cells use ligands to find the cell. Each cancer is specific in the way the cell is structured, so the bubbles are equipped with specific ligand that will only attract to Pancreatic Cancer cells. They won’t even target another type of cancer because each cancer is so specific.

October 9th – October 22nd (5.5 hours) – In the last two weeks I have taken my Laser Safety Training course, and I have had my internship site visit with Mrs. Polivchak. My Laser Safety Training course was a very valuable class that I’m required to take if I ever plan on building or adjusting the lasers I work with more closely. I learned all the different Laser classifications given by different Laser Safety organizations. The UofA is required to follow all of the rules for each of the different laser classifications while the lasers are out of storage. At the end of the class I took a test, and based on how well I do on that test will determine if I passed the training. Then I had my internship site visit with Mrs. Polivchak, where I was able to listen to my mentor discuss my performance. He decided that I’m doing well, but I need to ask more questions because of how hard it is to understand all of the physics behind the laser work we do. I plan on taking this guidance, and now that I understand the basics of lasers from my Safety Training course I hope to better understand the Multiphoton Microscope.

One term I was introduced to this week was mode-locking. It has to do with a process inside a laser that stops that laser beam in femtoseconds, creating a pulsed laser. By using a pulsed laser beam more power is built up each time the beam is stopped then allowed through. Because of this increase in the power, less power can be used to power the pulsed beam at the same output power as a continuous beam.

October 23rd – November 5th (6 hours) – In the last couple weeks I was introduced to a computer program called Photoshop. My mentor, Ben, has used it since he was little, and he uses it for creating diagrams to use in scientific papers. He showed me a couple of diagrams he’s made in the past of different types of lasers, and now I’m working on my own diagram for the Multiphoton Wikipedia page we’re writing. I’ve spent a couple of hours navigating my way through the tutorials and I’ve started my diagram over the last couple weeks. Then on Halloween we went to a Halloween party, where I met a lot of new people. Many of them were curious about how I was introduced to Optics, and a few were disappointed that I didn’t learn about it through school. Ben and I started talking about possibly having him speak at my school about Optics to get more people interested in the field. This year I’m taking AP Physics, and my teacher seems very excited to have an Optics student talk to our class and his Astronomy class.

Quite a few times I have worked with other students instead of my mentor, Ben. Mostly I have worked with Ryan on a few experiments involving the Multiphoton Microscope. We have imaged different materials, including a microchip, and we’ve started researching information for the Multiphoton Microscope Wikipedia page while Ben was studying for his Graduate final exam. I also have worked with another student named Sean on a current project he’s working on. Sean is building a fiber laser that will be used in another microscope he’ll build later on. So far we’ve spliced the fiber pieces together and measured how much power is running through it without mode-locking.

At the Halloween party I attended this week I was able to meet a lot of new people, including a few women from the Women in Optics club. They told me a little bit about what they do, and they invited me to a few of the events they’re planning. They were all very nice. There also was a costume contest and the entire club dressed up as pumpkin pi. They wore all orange with the mathematical symbol pi painted on them. I was hoping they would win, but they got second place to a couple who dressed as characters from Courage the Cowardly Dog Show. I don’t really interact a lot with coworkers on an entirely social level because I only see about two or three a day, and most of the time we’re working on long-lasting projects. However, being college students they often can get off topic, so our conversations aren’t usually the most scientific.

One term I learned a few weeks ago was actually L.A.S.E.R. Apparently the word “laser” is actually an acronym for Light Amplification by Stimulated Emission of Radiation. I learned it through my Laser Safety Course and my mentor has quizzed me on it a couple times since then.

November 6th – November 19th (3 hours) – At my internship site this week we decided to do something a little more interesting for my last day this semester. We collected our own samples from outside to look at under the Multiphoton Microscope. We picked flowers and leaves from various plants. We even grabbed a few pieces from cacti and a single lime we found on a tree. After looking at a lot of the samples we decided to take some pictures and create 3D images of many of the plants. This took the longest because the Multiphoton scans one layer at a time. We ended up with a lot of really interesting pictures, especially one of a moth that I plan on using in my presentation for SEP. The rest of the time I spent working on my microscope diagram that I will use in my internship presentation at the end of the year.

According to my mentor I was very punctual, and usually a little bit early. We established a very easy schedule to follow, so sticking to it throughout this semester hasn’t been difficult for either of us. One time I had to cancel on my mentor last minute due to a family emergency, but I made sure he knew right away and it all worked out. I plan on changing the schedule slightly next semester in order to make it easier to earn more hours. This semester I was very busy with band activities, so I wasn’t able to go more than once a week. Next semester band will have a lot less practices because football season is over and I will be at my site twice a week. Both days I plan to go will be easy to follow because it will be during my free sixth period, which should be the same every week.

I think I have juggled all of my schedules very successfully this semester. I have maintained a 4.0 grade point average, despite taking four advanced placement classes and a writing 101 class through Pima Community College. I also have made it to almost all of the band practices and drum major practices required for me to keep such a high position in the band. I haven’t missed a single football game, pep assembly, or band competition. I’ve missed a couple of Professional Development Meetings due to them being on one of my most busiest days of the week, but I have made them up, and I have met all of the requirements needed to keep my internship. My mentor complimented a lot of my time management skills in our meeting to evaluate my performance, and I’ve already managed to fix some of the things he criticized about my performance. I’ve managed all of this while taking care of my chores and five year old sister when my parents are busy with their own work. I will admit, however, that one area that has suffered is my sleep schedule. I’ve lost quite a bit of sleep from working on homework and just dealing with the stress of being a senior, but next semester will be very different. Marching band will be over because the football and competition seasons are over, so I will have time after school Monday, Thursday, and Friday, as well as time on Saturdays to get things done at a better time of day.

One term that I already knew, but never knew it was used in a certain way before was “figure.” When writing a science paper to submit to a journal you should add figures in order to get your point across more easily. A figure is a picture specifically designed for one purpose in a paper, usually by the scientist writing the paper. I’m designing my own figure right now and so far it has proven to be very intricate.
