‘All the cool historical (and sometimes modern) Ladies!’ : Rosalind Franklin

‘All the cool historical (and sometimes modern) Ladies!’ : Rosalind Franklin

It’s the end of March so after a month of fervent university work, I’m going to jump in with my first instalment of ‘All the cool historical (and sometimes modern) ladies!’. So I’m going to tell you about some wonderfully intelligent and awesome (do I say awesome too much? Probably…) lady scientists. Now these are only tit bits of their contributions to science,... »

Science Sunday:  Biometric Security and the Impermanence of Fingerprints

Science Sunday: Biometric Security and the Impermanence of Fingerprints

Recently, on my spring break (which now that I am not a student, I can take) I met a delightful older nurse who told me many fun stories about patients with bubonic plague and ebola.  That’s not important.  The important thing was that she also told me that at the clinic where she works, there is an atm-like drug dispenser that nurses must enter a passcode and have their fingerprints scanned... »

Fair Lady of Computer Science who Kicks Ass

Fair Lady of Computer Science who Kicks Ass

In honor of women’s history month, I am going to gush about how much I love Frances Allen.  Partly, because I’ve met her.  Well, I’ve attended a lecture she gave, which is not the same thing.  Also, because she has won the Turing Award, the highest honor the computer science community can bestow.  She is, incidentally, the first woman to win it.  It is fair to say that without he... »

Science Sunday: Does the Sum of All Natural Numbers Equal -1/12?

Science Sunday: Does the Sum of All Natural Numbers Equal -1/12?

They say not to write a post with a question if the answer is “no” but I’m going to do it anyway. You may have seen this video floating around the intertubes that claims to show that summing all the natural numbers (1 + 2 + 3 + 4 + 5 + … all the way to infinity) is equal to -1/12: As you may have guessed by the first sentence of my post, the sum of all the natural numbers d... »

The Physics Philes, lesson 80: Oscillation, Conservation, Physics-ification!

The Physics Philes, lesson 80: Oscillation, Conservation, Physics-ification!

We’ve learned a lot about simple harmonic motion over the past several weeks. We’ve learned how to find the velocity, acceleration, and displacement of an object in SHM. Now we need to integrate energy into our understanding. Let’s think about our object oscillating at the end of a spring. The only force that does any work on the oscillating body is the horizontal spring force. A... »

The Physics Philes, lesson 79: That’s So Derivative

The Physics Philes, lesson 79: That’s So Derivative

Last week I said that this week I would write about the period and amplitude in simple harmonic motion. Well, I changed my mind. We’re doing displacement, velocity, and acceleration in simple harmonic motion, instead. (What? I don’t see you writing a weekly post about physics.) Anyway, let’s begin. We’ve learned how to find the frequency and period of SHM. Now we move on to... »

The Physics Philes, lesson 74: Motion of Planets

The Physics Philes, lesson 74: Motion of Planets

In case you haven’t been keeping up, we’ve been learning about gravity for the past several weeks. Last week we saw how the universal law of gravitation tells us how satellites orbit a planet. Gravity is also a really important part of planetary motion. That’s what we’ll be talking about today. When we talk about planetary motion, we have to discuss Kepler’s laws of p... »

Science Genius: hip hop remixes science

Science Genius: hip hop remixes science

Science Genius is a pilot program to teach science in schools using hip-hop and rap. Check out its progress so far in this video with ninth graders from Bronx Compass High School. Although it’s not the same program as the rap battles that Mindy has been posting on Fridays, it follows a growing trend to make science a little more accessible to everyone. (For more on Science Genius, check out ... »
