Intro to Relativity

By: Miranda Copenhaver, Chloe Nash, Wanda Wilkins, Lauren Behringer, and Jazmin Santillan C.

 

Throughout this week, we have worked through multiple problems dealing with both classical mechanics and special relativity. We found the main difference between classical mechanics and special relativity to be the assumptions made about time as a constant. This is what we mean:

  • In classical mechanics it is assumed that time is a constant that is observed the same for all viewers.
  • In special relativity time cannot be taken as a constant. Because the speed of light is the same for all observers, time-dilation occurs.

So, if you are getting a little lost it’s completely normal. We have a couple of examples of both classical mechanics and special relativity below:

Knot Theory @ WPI

by Knot Nerds

What is knot theory?

Have you ever tied your shoes before? I mean, I hope you have! So, what in the world does tying your shoes have to do with math? Here comes knot theory! Knot theory is a sub-topic of topology that studies mathematical knots, links, and their permutations. Knots can be represented by polynomials and can thus be compared to one another.

RSA Cryptography @ WPI

By: Jourdan Moore, Emma Holzbach, Nicole Godwin, Naa Aryee, and Athalya Wakonyo

Have you ever made a secret language or code with your friend so that only you two would know what’s being said? You’re in luck! With the help of RSA Encryption Cryptography at Girls Talk Math we’ve learned about the world of mathematics, more specifically RSA, as well as  Modular Arithmetic, Greatest Common Divisor and related theorems.  

RSA is one of the first public-key cryptosystems created by Ron Rivest, Adi Shamir, and Leonard Adleman in 1977, and is now the most widely used cryptography algorithm in the world.

Schoolhouse Rock—Dr. Candice Price Rocks!

By Clara, Ceren, Zoe, and Jess

Dr. Candice Price had always been good at math. But when her third-grade teacher presented “Schoolhouse Rock!–Multiplication Rock!” to her class, her passion truly began. The 30-minute multiplication lesson inspired her everlasting enthusiasm for mathematics. It is this inspiration that drove her to be the accomplished female mathematician that she is today.

Alice Silverberg: A Snapshot of her Mathematical Career

By: Claudia, Meghan, Elizabeth, Yunjing

Born on October 6, 1958, Alice Silverberg is a 1979 Harvard University graduate who then received her master’s degree and Ph.D from Princeton University under the supervision of Goro Shimura. Her academic career began at Ohio State University where she worked as an Assistant and Associate Professor of Mathematics from 1984 to 1996. In 2004, she moved to the University of California, Irvine as a Professor of Mathematics and Computer Science. For the next twenty years, Silverberg gave lectures at universities around the world and served as an active member of the nominating committee of the American Mathematical Society. Since 2008, Silverberg has worked as an editor for the Association for Women in Mathematics. She is also the writer of her own blog, Alice’s Adventures in Numberland, where she addresses prominent social issues of sexism and discrimination in her field.

Quantum Mechanics

By Izzy Cox, Divya Iyer, Wgoud Mansour, Ashleigh Sico, and Elizabeth Whetzel.

Quantum Mechanics is the physics of molecular and microscopic particles. However, it has applications in everyday life as well. If someone asked you if a human was a particle or a wave, what would you think? What about a ball? What about light? Not so easy now, is it? It turns out that all of those things, and in fact, everything around us, can be expressed in physics as both a particle and a wave. This might seem a little unbelievable, but for now, let’s start with the basics.

 

Classical Physics

Although Classical Physics sounds like a complicated idea, it’s the most simple branch of physics. It’s what you think of when someone says “physics”. Classical Physics lays the basic foundation to Quantum Physics with a few basic laws.

Quantum Mechanics

by Nya Batson, Monique Dacanay, Emily Gao, and Staci Tranquille.

Hello! And welcome to the realm of quantum mechanics!  First off, what in the world is quantum mechanics? Let’s start with a brief introduction.

What is Quantum Mechanics?

Quantum mechanics is one of the most important branches of physics. It focuses on the laws of nature at three different levels: molecular, atomic, and subatomic. Quantum mechanics has a variety of important concepts; the following are some that we learned through our problem set: Planck’s law, the photoelectric effect, and wave-particle duality.  A crucial element of quantum mechanics is understanding that everything has characteristics of both waves and particles. We will touch on this and many other topics later on.
