Can I Find Any 1964 Silver Quarters?

“Hey, look! There’s a big container of coins. I wonder if there’s any 1964 quarters in there.” That’s how it started and here’s how it ended. A short history of US coins Maybe you already know this, but I will...

Is This A Good Math Question?

Everyone loves standardized tests, right? They are just super awesome in my book. SUPER AWESOME. Here in Louisiana there is the LEAP test. I don’t know all the details, but I think students have to have some minimum score in...

How Much Does Captain America’s Shield Weigh?

Check out this short clip from the next Captain America movie: The Winter Soldier from Yahoo. At the end, Cap throws his shield at the Winter Soldier – because that’s what Captain America does. But wait! The Winter Soldier just...

When Will I Get One Million Twitter Followers?

It seems that the primary objective of the Lucretius, ver. 21c blog is to compile statistics on the twitter accounts of the top physicists, philosophers, and astronomers. Occasionally, there are posts that show the growth of different accounts. In particular,...

Calculating Pi For Pi Day

Happy Pi Day to you and everyone around you! I always like to find something cool to do with pi on Pi Day. What if I just try to determine the value of pi without using pi (which seems obvious)....

Could Captain America Jump Without a Parachute?

I am moderately pumped up about the next Captain America movie: The Winter Soldier. The above clip is pretty exciting. It shows Cap jumping out of an aircraft without a parachute and then landing in water. Clearly this isn’t something...

Book Review: The Art of Tinkering

You might have noticed that I don’t do too many book reviews. Why? I guess that’s just not one of the blogging options that I perform very well at. Also, reviewing books can take a serious chunk of time (but...

Why Can’t We Have Hoverboards?

Yes. The recent hoverboard video is a fake. Really, it was obvious. Tony Hawk couldn’t take the subterfuge any longer and had to confess. He felt that everyone would know the thing is fake. Clearly, Tony hasn’t been spending enough....

Could You See the Curvature of the Earth in this Airport?

Traveling can be boring sometimes. What happens when I get bored? I look for interesting problems and calculations. Above you can see the airport terminal inside the Atlanta airport. If you happen to be in there during a low traffic...

Could The MythBusters Shoot a Cannonball Made of Ice?

You can shoot all sorts of things from a cannon, but can you shoot a ball made of ice? The MythBusters set out to test that myth in their next episode, but let’s first think about the physics of an...

The Hidden Physics in MythBusters Bullet Baloney

In the MythBusters Bullet Baloney episode, a variety of bullet myths were tested. Each myth has some interesting physics but there is some hidden physics in this episode also.   Let’s take a look at some of the less obvious...

Sochi Physics Homework

The 2014 Winter Olympics are finished (in case you didn’t know).  The Olympics are filled with interesting physics problems.  If only I had more time, each of these could have been a nice blog post. Instead, it’s up to you...

What Is the Slowest Running Speed For a Loop-the-Loop?

I’ve looked at the loop-the-loop problem before. The basic idea is to take something (like a car) and drive around a vertical loop while not leaving the track. It’s a cool stunt especially with a human. How does it work?...

Godzilla Gets Bigger Each Year

I bet you thought Godzilla was godzilla-sized. Well, you are wrong. Godzilla is BIGGER THAN GODZILLA. Check out the new poster from the next version of Godzilla movie. That’s a big Godzilla. BIG. io9 has an interesting post that includes...

Isn’t This Physics and Not Computer Science?

My new plan in introductory physics is to require students to demonstrate some ability to create a numerical calculation. Just to be clear, by “numerical calculation” – I mean to solve a problem by breaking that problem into many simpler...

Do Uniforms Make a Difference in Speed Skating?

It seems the USA speed skaters aren’t doing as well as they had hoped to in the 2014 Winter Olympics. One idea is that the new uniforms could be part of the problem. I don’t know much about skating, so...

Angry Birds: How Do You Change Red to Pink?

Surely, you know of Peter Vesterbacka. Right? Well, it seems like he always is wearing his signature Angry Bird red hoodie. Well, I was a bit surprised to see him with a Pink Stella hoodie on as he posted on...

How Fast Can a Skater Turn in the Speed Skating Short Track?

In the Olympic event of Short Track Speed Skating, athletes race around a rather short track (thus the name of the event) that only has a circumference of 111 meters. It always seems almost magical the way the skaters lean...

How Much Would a Real Olympic Gold Medal Cost?

In some news item, it was pointed out that an Olympic Gold medal is made with only 1% gold. Ok, that makes sense. A full 100% gold medal would probably quite expensive. Also, gold is a rather soft metal so...

How Difficult is Flappy Bird?

I have to write something about Flappy Bird to make sure that Frank (@fnoschese) doesn’t get too far ahead. Oh, you should go read his awesome analysis of Flappy Bird.  It was very impressive. I can’t imagine that you have...
