That's an initial velocity from a jump.  Usain Bolt is looking at his whole body running where 12.27 m/s is a sustained speed.

Kind of like a donut -- it's hard to tell the beginning and end.  Well, unless you eat it, and the first bite is the beginning, and the crumbs are the sad end.  

I really think you need a bowl of ice cream.  With rainbow sprinkles.  Perspective, HegelBot, perspective...

Happy birthday to Mr. Gauss!!!

It is the study of everything...

Great stuff here... I've used circuits.io before, but hadn't seen tinkercad!

Ever wonder how you make a logic gate?  http://www.aplusphysics.com/courses/honors/microe/microe.html

Starting to go off the rails a bit again... if you haven't been giving best effort, do so.  Kick yourself in the fanny and get on with it.  And if you have, be proud of what you've done and continue on.  Regrets disappear when you give it your all.  So get to it!  

Absolutely.  Or write about what would happen if instead of a sphere, Earth was a disc.  Or a ring (Discworld, anyone?)  Figure out the thermodynamics of a Harry Potter spell, or the acceleration of Ironman in a Marvel movie.  Make it fun.  

My goodness, not sure where to begin here HegelBot153...  laughing over the blatant shilling for the APC Companion.  

Nice post HegelBot153.  If you wear flannel pajamas and have flannel sheets, rolling over under the covers can be an 'enlightening' experience as well!

I sent the WebAssign folks this blog post.  Haven't heard anything back to date...

Great job finding applications of physics concepts to the wider world!

I'm still trying to figure out why, if they could take out the death star with the ramming/light speed maneuver, wouldn't you have done that with the FIRST ship to run out of fuel?

You're more than halfway there... keep up the good work!

I agree... would be much more exciting if it actually dropped in free fall!

Would you like it to?

Wow, we're in agreement on something!!!  I think Dr. Tyson does some wonderful things, but also believe there's further opportunity for respecting and leaving room for the thoughts of others.  Which I imagine he does internally, though at times his external image seems to cling more strongly to the black-and-white (which is part of being an entertainer).

Close, but as the angle in radians approaches zero, cosine of the angle won't approach zero... it should approach 1.

And THIS is why I avoid New York City...

Fantastic blog post, and a great start on understanding some of the conceptual ideas around time dilation!

Full contact billiards... cool!
