Spinning Light

Adding Light

Today, I experimented about the color that forms when light mixes. I spun a disk with the colors red, yellow,
orange, green, purple, and blue on a DC motor. This plays a trick on your eyes because whenever you look at it , it spins quicker than 1/15 of a second so it looks like the colors are joining. How does it look? You will
soon find out

Question: 

What color do the rainbow colors  make when they join together?

Hypothesis: 

I think they make white when the colors join.

Research: 

Colors of the rainbow are caused by prisms.

Experiment:  

You will need 2 wires, 1 d-cell battery, a DC motor, a battery rubber band, and a disk with colors of the rainbow.

Materials for experiment

Doing experiment:

  1. Put the rubber band around the battery. 
  2. Attach one end of  the two wires to each side of the battery under the rubber band.
  3. Attach the other end of the wires to each side of the  DC spinning motor
  4. Put the disk on the point of the motor

Analyzing Data: 

There were six colors in the beginning, and now it looks like one color, white.

Conclusion: 

Yes, white is made when red, yellow, orange, purple, blue, green are added together.

My Summer

-
So today is Saturday, October 7th. Yesterday was the end of Week 1 of the quarter, meaning that we have about 10 more weeks before Winter Break, which doesn't seem like a lot. Summer this year was eventful. Firstly, I joined Smash Gyms for about two months, which I attended in the evenings after coming home from my internship. I attended the Muay Thai and Strength/Conditioning classes mostly. Secondly, I interned this summer at the same place I had interned at last summer, Cadence Design Systems. I enjoyed my time there and I didn't feel very stressed. Thirdly, during the last three weeks of summer break, which were also roughly the first three weeks of September, my parents went to India, leaving me and my brother to take care of the home, which we did. Now that I am growing older, I feel that I should be more careful about the words I choose, particularly on a public-facing blog like this one. There are pros and cons to this blog being public. The self-critical voice inside m...

Thoughts on LLMs and Modeling

-
I am sharing here something I have written about LLMs and modeling. Most of it leans towards the science-fiction side, but it is at least partially based on reality and hopefully it will serve as a foundation for some future research ideas. Hope you enjoy! https://drive.google.com/file/d/1He_KZDnfAaKOfcLkrfY_XVwMsHLmdhHK/view?usp=drive_link

A Realization

-
I just realized something that is simultaneously great and terrible--that hard work is the key to satisfaction. It is great because it means that if you work hard, life will be better. But at the same time, it is terrible because it means that you have to work hard even if you don't want to. I woke up around 8:30 full of fear, worry, and frustration. After I finished a long day of work (~10 hrs work at least I think), however, I feel satiated and fine. I still have a lot of work, but I feel a little calmer. I also had a random thought a few days ago that I thought I would talk about. Religion seems like not just one thing but rather a combination of multiple things. It is the stories and literature or mythology that comprise the story it tells. E.g. The Ramayana It is a set of rules by which you must live your life and tells you your values. E.g. The Ten Commandments It is your personal relationship with God. It is a source of comfort and love to help you get through tough times an...
