I spent some time looking at extruded aluminum profiles a few months ago and the cheapest place I found was tnutz.com- I never ended up buying anything though, but their stuff looked good as far as I could tell.

Turns out that when you overheat the economy by printing money and giving it to people for free, people buy so much stuff that most producers are running at capacity and can sell at high margins.

An honest analysis that seeks to understand the best level of regulation for testing of new drugs must consider both the people that will die due to inadequate testing and the people that will die from drugs never being developed (or being

The way the lithium brine is extracted from the ground is by pumping water down, allowing the lithium brine to dissolve in the water, and pumping it back to the surface.

Just about any car can brake hard enough to lock up all 4 tires and enter a skid (or activate ABS to avoid this)- the limiting factor to braking distance is friction between the tires and the ground. Scaling for static friction between rubb

One thing I find troubling about environmentalism is that the tendency to try to make everything more energy efficient/ optimized for the environment risks throwing the baby out with the bathwater in a few ways: -More expensive energy

One risk factor that makes me feel like the world is crazy is how terrible visibility is becoming in newer cars. A and B pillars are getting bigger and bigger, sightlines in the rear view mirror are getting worse too. There is a big problem

Where does the induction stove measure the temperature? I'm assuming there's a thermometer near the surface of the stove, which I guess is close enough to the food to get good results.

You could still spend 1,000 hours painting a blue dot on a white canvas if you used a tiny paintbrush. The pareto frontier of possible artworks approaches higher quality with increased labor input. This doesn't mean the Labor Theory of

Couldn't agree with this more. The idea that D&D has hoovered up so much of the world as to deny people of their own creative expression is absurd and I couldn't get past the first paragraph without thinking the author is off

IIRC there's existing case law in copyright law about the amount of creative work required to perform "transformative work" to an existing work. I figure that essentially, if you barely touched up the photos, you'd not h

I spent months trying to get a valve to pass the API 622 fugitive emissions test. It never passed before I got laid off. I suspect that valve stem packing for valves at methane plants is one of the leading contributors for this.

Turns out that the big 5 have predictive power. Hard to call it "tea leaves" if it has broad correlates with human behavior that are replicable across cultures and predict forward-looking behavior.

work= energy = force x distance (integrated if force is variable). Stick a load cell on a linear slide, measure accordingly.

In Illinois most of the wear on the asphalt surface occurs via ice and snow causing potholes. This happens over time regardless of heavy traffic.

If you think that a lightweight drone will give just as much wind power as a heavy helicopter, you need to think about F=MA a bit. The weight of the pilot (and supporting systems) act as balast against which the "fan" can push. O

For short flights, I do not mind the development of "standing seats." Airline margins will remain razor thin and the savings will be passed to the subset of customers who choose to be more cramped. There WILL continue to be "

I think that this problem, that you fear will cause no local reporting to happen, will cause local reporting to still happen. It's just that the local reporting will be poor quality.

I'm having a hard time confirming it (can't find the original paper w/o a link), but you are probably referring to mechanical stress instead of fluid pressure. if you hang a tensile load of 1000 Newtons from a 1mm x 1mm rod,

I like that design idea for the rotating disc. It makes me wonder the best way to stress the material while on the "compressed side." 1. Make the edge of the disc rub against a low friction, spring-loaded compressing element (simi

A few thoughts after reading this as a mechanical engineer: 1. My understanding: this material relies on mechanical work (force x distance = work energy) to add energy to the material by compressing (or tensioning, or "magnetically str
