With train travel being essentially 1-dimensional, it’s mind-boggling that there aren’t more safety systems to automatically slow trains down on sharp curves. It’s pretty simple simple physics to determine how much to slow down to take a curve safely.

The cool thing you didn’t mention is that 3D printing allows for highly optimized geometry to be manufactured. That weird pattern is a typical topology optimization result, likely optimized for stiffness in this case.

This is true even for the highly technical presentations in my field. With bad presentations I see at conferences, the common theme is that the presenter jumps off into the deep end with equations and theory. Even us nerdy engineers like for a proper story setup to understand the motivation behind someone’s work.

“Operator error” is not the answer here. Any time you provide an automated solution for something, there should be safeguards against failures this simple. I work for a software company but the principle is the same.

Still prefer the overhead bin if at all possible... I’ve been required to gate check before and ended up waiting ~10+ minutes for my bag. Not ideal if you have a 45 minute layover in Atlanta, with gates at the opposite ends of the airport.

Could have been much worse; at least it didn’t fly up into either of the rotors.

Was drooling until I saw that white interior. Not practical for this vehicle, aside from the fact that it’s hideous.

This is... fantastic. I’m so glad we have the internet.

The launch could be impressive beginning at T+ 2 minutes 12 seconds when simulations show the exhaust plume will be illuminated at high altitude by the sun

5 years ago, I definitely would have said too many ports...

Yess.. some days it does fee like there are a 747's worth of people packed into a 737.

I wonder if those rovers would still work with a fresh battery. Aside from solar degradation of exposed fabrics, plastic, and rubber, I would assume the internal hardware is in pretty good shape...

That actual means something in the engineering world. We differentiate between “analytical” analysis and “numerical” analysis. Analytical is usually closed-form equations that can be solved on paper. Numerical analysis involves thing like FEA and other computer simulations.

Those mail carriers better not be using AC with my tax dollars!

It’s the distance, not time that matters with electric cars. The battery isn’t doing anything when the car is stopped, unlike an idling gas engine.

I have 10 Insta followers. Was being optimistic when I clicked on this post, but now I realize I have some work to do.

Open up the chapter, but don’t read any of the regular-sized text. Instead, read the subject headings, try to figure out what those charts are trying to tell you, and pretend that those big multi-part diagrams are the only thing you have to really understand

Came here to say something similar... currently drive a 2004 A4 manual and absolutely love it. Probably will only get a few more years my current car, so I’ve been looking around a bit. But it’s all slim pickings for manuals these days.
