Should Dwarves Stand Up in Floating Barrels?

10 months agoAcademics / Physics : Dot Physics

Surely you have read The Hobbit (the book). It’s a classic novel and the basis of the upcoming movie The Hobbit the Desolation of Smaug. The book is old enough that I don’t think I need to give any spoiler...

I Am Code and So Can You

10 months agoAcademics / Physics : Dot Physics

The Hour of Code is simple. Just go to and click the START button. Yes, it is really that simple. There are quite a few tutorials at several different levels and in several different programing languages. But the real...

How Do You Pick Up Something on the Moon?

10 months agoAcademics / Physics : Dot Physics

During the Apollo 16 mission, Charles Duke dropped his hammer. What do you do next? You pick up the hammer, right? NOT SO EASY. Why is this such a difficult task? It's a combination of the lower gravitational field on...

Numerical Calculations Can Seem Like Magic

10 months agoAcademics / Physics : Dot Physics

I’ve written about numerical calculations before, but perhaps they weren’t too inspiring. What are numerical calculations? Here is my own definition. Numerical Calculations (numerical methods, computational methods): The process of taking a complex problem and breaking it into many smaller...

Physics of the Amazon Octocopter Drone

11 months agoAcademics / Physics : Dot Physics

I, for one, welcome our Amazon drone overlords. There, I said it. This seems crazy. The basic idea is that these little drone copters would carry small packages to nearby homes. What does physics have to say about this plan?...

Do Comets Zoom Across the Sky?

11 months agoAcademics / Physics : Dot Physics

Note: I wrote this before comet ISON had it’s close encounter with the Sun.  The first reports were that ISON had broken up and not survived the intense sunlight.  That made me sad.  However, it seems that ISON is just...

How Many Batteries Would It Take to Cook a Turkey?

11 months agoAcademics / Physics : Dot Physics

What’s more fun than cooking a turkey? The answer: thinking of new ways to cook a turkey. I’ve already thought about cooking a turkey by dropping it, but what about something else? Of course, the goal here is to use...

How Do You Explain the Tides in 10 Seconds?

11 months agoAcademics / Physics : Dot Physics

How do you explain ANYTHING in just 10 seconds? Well, it’s pretty tough. Of course, you can’t tell the whole story in just 10 seconds (unless maybe you talk super fast). Well, this is just what Henry Reich of MinutePhysics...

Reflecting on TED Youth

11 months agoAcademics / Physics : Dot Physics

Yes, I was at this year’s TED Youth conference in New Orleans. It was a lot of fun. Here are some of my random thoughts on the whole thing. Some Impressive Talks I can’t remember exactly what I was doing...

How Do Things Cool With Evaporation?

11 months agoAcademics / Physics : Dot Physics

You know water evaporates – that’s when it turns from a liquid to a gas. You probably also know that a hot pot of water will cool off in part because of evaporation. However, did you know that a cup...

Modeling a One Dimensional Collision

11 months agoAcademics / Physics : Dot Physics

I shouldn’t write this post, but I can’t help myself. I’m weak. This all started with some videos I made for a lab. The idea was that the students could use video analysis to explore these collisions. Video analysis works...

Video Analysis of a Tank Round

11 months agoAcademics / Physics : Dot Physics

Personally, I’m not a big fan of being fire at by a tank – it’s just a personal thing. However, in this case it looks like the tank is fired at some type of remote camera (hopefully). Speed and Distance...

Security Theater and Learning Theater

11 months agoAcademics / Physics : Dot Physics

Here is Security Theater as defined by Wikipedia. Security theater is the practice of investing in countermeasures intended to provide the feeling of improved security while doing little or nothing to actually achieve it. Actually, it seems that this definition...

Does Smaug Have Enough Gold?

12 months agoAcademics / Physics : Dot Physics

I guess dragons love gold. In the recent trailers for The Hobbit: The Desolation of Smaug (Youtube clip) you can get a glimpse of all the gold Smaug has. Why does a dragon need this much gold? I don’t get...

Numerical Calculations With Guass’s Law

12 months agoAcademics / Physics : Dot Physics

First, I would like to blame Frank Noschese (@fnoschese) for this post. Some time ago, he posted this on twitter. Unwinding by writing VPython code to brute force calculate the electric flux thru the face of a cube. #iknowyourejealous —...

A Media Guide for Physics

12 months agoAcademics / Physics : Dot Physics

Hello people in media – mostly I am aiming at television shows, but this might apply to many different areas. So, I hear you are putting together a show with SCIENCE for people who like SCIENCE. That sounds great. Let...

Physics of the New SHIELD Helicarrier

12 months agoAcademics / Physics : Dot Physics

The trailer for Captain America: The Winter Soldier shows off the new and upgraded S.H.I.E.L.D. Helicarrier. Among the improvements: more thrust and a jet-engine look. Why?

Lies, Damn Lies, and Progress Bars

12 months agoAcademics / Physics : Dot Physics

Wired Science blogger Rhett Allain suspects his computer lies to him about the time remaining to download software. So he uses science to prove it.

A Mole of Humans

Happy Mole Day. Yes. Mole Day. Just about every month this is some special day. There’s Gravity Day, e-Day, Pi-Day, and Talk Like a Pirate Day. Mole Day celebrates the mole unit. That same mole you saw in chemistry class...

Where Is the Accelerometer in an iPhone?

Actually, I’ve done this experiment before (although with an iPod touch). Of course, it’s a fun experiment so it seems worthwhile to repeat the measurement. Of course most smart phones have some type of accelerometer so that you can do...
