If you can’t fix it, you remove a few links from your chain and turn your bike into a single-speeder until you get to the next city, where you check into the local hostel to find another cycle tourist awaiting the return of their Rohloff hub or Pinion gearbox from Germany. You find...
While I have several videos discussingthe topic of deep-sky astrophotography on myYouTube channel,I realized it was time for a thorough walkthrough of my entire current process (as of 2023) forcapturing deep-sky images with a camera and telescope. This article aims to accomplish that goal by...
A few years ago, I wrote a short document on methods for rapidly fabricating elements of mechanical systems entitledHow to Build Your Robot Really Really Fast. It was catered towards students in MIT's2.007introductory design and manufacturing class for which I was a lab assistant at the time. ...

I will have a homogeneously wet pavement (along with a water friction force on the bottom of the wheel) so ##\mu## might be changed between simulations but...
One of the most primitive types of gears we could look at would be a wheel with wooden pegs sticking out of it. The problem with this type of gear is that the distance from the center of each gear to the point of contact changes as the gears rotate. This means that the gear ratio ...
To find the best locations, head to a dark sky site far away from any light pollution. In warmer, summer months you may even spot nocticulent clouds at twilight.(Image credit: Stuart Cornell) When it comes to lenses, you will want to purchase the 'fastest' lens available and depending ...
We can use (x, y) coordinates to describe any point along the outer edge of the circle. The x value or x-coordinate represents the distance traveled left or right from the center, while the y value or y-coordinate represents the distance traveled up or down. The x-coordinate is the co...
of charges—and the remainder. We thereby find a symplectically corresponding decomposition of the gauge potential into a part that is pure gauge and a remainder: call themXandY, respectively. If we single out the scalar degree of freedom of the electric field that is fixed by the Gauss ...
