That awkward moment when …

You publish a video about a similar topic as another YouTube channel, namely Vsauce, within a day of each other and everyone decides to comment on that fact instead of how awesome it is that I am breathing the same air molecules as Albert Einstein may have used when he figured out the theory of relativity. 

I mean, at least we could comment on how I totally catch that soccer ball in the opening scene without looking at all?! I’m like a science ninja. Bam. Ball = caught. 

Anyway, I think both videos are great and clearly great minds just occasionally think alike! Not only do we share the same air, but we can also share the same ideas. That’s pretty neat. :) Thanks to all the people who are leaving constructive comments instead of negative ones. 

For those of you who enjoyed yesterday’s thought experiment/mindfreak about how our perception of now is never really “now”, check out this episode of Vsauce.

This video starts with a focus on the time lag that occurs in our visual system, and how what our brain tells us is “now” is actually 80 milliseconds in the past. He also digs into the question we talked about with simultaneous tapping of noses and toeses.

The more we talk about this, I just can’t help but think of a particular scene from Spaceballs:

Colonel Sandurz: Now. You’re looking at now, sir. Everything that happens now, is happening now. 
Dark Helmet: What happened to then? 
Colonel Sandurz: We passed then. 
Dark Helmet: When? 
Colonel Sandurz: Just now. We’re at now now. 
Dark Helmet: Go back to then. 
Colonel Sandurz: When? 
Dark Helmet: Now. 
Colonel Sandurz: Now? 
Dark Helmet: Now. 
Colonel Sandurz: I can’t. 
Dark Helmet: Why? 
Colonel Sandurz: We missed it. 
Dark Helmet: When? 
Colonel Sandurz: Just now. 
Dark Helmet: When will then be now? 
Colonel Sandurz: Soon. 

Is The 5-Second Rule True?

I’ll go ahead and spoil the answer to that question and tell you no, it is not true.

But you won’t believe just how interesting the world of touching, not touching, and the shake-rattle-and-roll of molecular interactions can be. And when you find out how many little bacterial bugs are living on the things that you touch every day, you might decide to live in a plastic bubble for 2013. Great video from Vsauce.

Minute Physics: What if Earth were hollow?

There are still kooks out there who swear the Earth is hollow, but what if that were really the case? Minute Physics examines.

You’re gonna want to watch this obviously.

But be sure to catch Part 2 over at Vsauce, where you will learn about why astronauts just can’t stop falling, find out why you shouldn’t fire guns on the Moon, and how much water it would take to put out the Sun (except that you can’t).
