Good points - but here the ink is still trapped in its enclosure and we don't want it to spread at all when we're not writing.

My favorite least exciting experiment!

Maybe, if it’s not about a bottle of water where we don’t want anything to flow out, one could use some sort of Transparent Material At The End Of A Gel Pen Refill to close the plastic pipe and prevent exposure to air to prevent evaporation

Only if there is no propulsion and whatever goes through the tunnel exclusively relies on gravity.

“Gel ink is viscous, but it’s not thick enough to prevent it from flowing. This means it can evaporate over time” These are three different, unrelated phenomena. In a Newtonian fluid, no matter how large the viscosity, the fluid will flow w

Can’t upvote this enough. I actually include an hour of rant in my Fluids class where we dissect CFD results from blogs or LinkedIn - hypersonic reindeer for Christmas are fun and obviously a joke, but everything presented sincerely, like a

Not only the engine - but in Huntsville you can see two Saturn V launch vehicles! A mock up standing, and the other one made of actual stages (not intended to fly, though). The only other places you can see the Saturn V are the Johnson Spa

It's not, though, the Venus atmosphere does not behave like an ideal gas all around, it transitions into a supercritical dense liquid towards the ground.

Frankly, I can't even tell if you're just being sarcastic at this point.

Yes I understand. Imperial is awesome because you can divide a foot by exactly 2, 3, 4 , and 6, which of course, is the main problem everyone has every day. Metric on the other hand sucks because none of my measurements will ever be nice ro

The thing is, though, that you have these conversions even within the imperial system ( https://en.m.wikipedia.org/wiki/Imperial_units#/media/File%3... ) but not within the metric system. My experience with U.S

Granted, I am biased towards propulsion, but we are not talking about some bolt or bearing as a 'single component'. The propulsion system is a complex thermodynamic cycle, with tanks, turbopumps, preburner, regenerative cooling, i

Given "Planck's Principle"of "Science progresses one funeral at a time", it does not seem that scientists within the system will be the best to figure out who should be favored over them. That second group cannot em

The thing is that we often don't even know it. Einstein did not solve a pressing problem with his theories of relativity.

I agree with 'courage', but the problem is that it all depends on the courage of the people with money rather than the courage of the researcher. Someone has to take the risk and hire you for a tenure track position, and someone h

By that logic essentially all cryogenic engines are “the same”.

I don’t understand your first paragraph - is this related to the F-1 development having strong iterative components? Also, Combustion instabilities date back to at least the A4/V2, not quite new, and largely the same engineers.

by bernulli 6y ago
I’m not sure 3200 full scale tests of Saturn V’s F-1 engine, 2000 in an iterative trial-and-error scramble to suppress combustion instabilities is what I would call “overengineered to cut out iteration” during Apollo http://www.

I'd argue everyone who has heard of Ford is most likely familiar with Mercedes, whereas the number of people familiar with Amazon will likely be many orders of magnitude larger than the people who know who invented cloud computing. Not

Thank you for adding substance to my post!

It was rather a project by then Chancellor Gerhard Schröder to make sure he had a nice retirement fund and was indeed hired by Russian Gazprom right after he left office. Now the question is whether Germany honors these arrangements or not.

The article you linked makes no statement about the origin of that first dip. Regardless, whatever dips there are, this is completely unrelated to him using his position for personal gain, which is the original discussion here.

That’s not what the article says at all. It says that his hotel businesses went south due to COVID. That’s orthogonal to the myriad ways he extracted money from being a president.

I did not define what I meant by socialized health care, but I meant it in a positive way. Everyone is insured, and your insurance is not bound to any employer. Ironically, this means there is some actual competition in Germany (or at least

I agree with all of this, and certainly with your correction of my sloppy wrong comments (wrong numbers). Further, what you sketch out in the second part is exactly my biggest squabble with Germany. Let's see how a society that lives o

I’m curious, which part of 36hrs/wk work, a legal cap at 40hrs/wk, 6 wks of vacation, 2 yrs of parental leave, socialized health care, college (essentially) for free, etc, is the most horrendous part for you about being a worker i
