NumericUpDown in Windows Forms and a small acceleration hack...

Since I've been chatting about acceleration, I figured I'd point out how and where these types of methods could be used to make your life simpler and how sometimes a basic hack will do. The first exercise is going to be taking a NumericUpDown and setting...

Physics Quickie: Consistency of Measure

Sometimes maintaining consistent measure in a physical equation is the most important feature determining the final result. Many people get confused as you start to throw mass, length, and time together to create what are called derived units. For instance...

Physics Quickie: Interpolation over time. Following the bouncing ball.

All of the equations are done, but it seems applying them may still be confusing. Check out the previously defined equations and then come back here to see how they can be quickly and easily applied in a simulation Physics Installment #1: On the road...

Physics Puzzler: In the Newton's Cradle, why do two dynamic balls eject two static balls

I was actually going to post something on this and then I figured I'd do a quick check of the available literature. Seems someone has explained the cradle in far more detail than I would care to so you can check out his explanation when you think you...

Physics Installment #1: On the road to collisions

My math installments have been very popular, but I really need to jump into a more specialized mathematics in the form of equations that pertain to physics. We are going to be covering the basics of collisions today. These are very basic, in that we'll...

That was one hell of a Men's Track 400m event.

Getting gold in the Men's 400m is one thing, but getting the silver and bronze as well, now that was just too cool. I don't think most people can appreciate how fast these guys are running though. First, they are running 400 meters. The normal runner...

Math Quickie: Relationship between arc distance and linear distance.

The first concept is displacement. This is the change in location at two particular points in time. If something happens between the two times we choose, we don't consider that for the equations. That means you could drive your car to work and back home...

People spend a lot of time solving the traffic problem, but I always figured they were further than they really are...

People that enjoy math tend to appreciate complex problems, especially problems that have more than one solution, and possibly more than one optimal solution. That makes traffic congestion an ideal problem for people to try and solve. Using Seattle and...

A painful book on Quantum Computing, but probably a good read for one not familiar with the literature.

The book of the day is The Feynman Processor : Quantum Entanglement and the Computing Revolution (Helix Books Series) , and I'm going to give both a description of the book and a quick intro to quantum computing and my thoughts on the current state of...

Pimping another physics book: "Three Roads to Quantum Gravity"

Three Roads to Quantum Gravity Trying to understand the thought processes and devices that physicists create in order to define the universe is an awesome process that I recommend for anybody. The constantly create tools that have no natural relationship...
