The definition was actually for 4 °C, the point at which water is most dense. At 20 °C the density of water is about 0.997 g/mL. However, we don’t use water to define the metric system anymore, so even at 4 °C - or more precisely 3.983035(670) °C - water is not exactly 1 g/mL.
So they should arrest Israelis on sight too right?
Very cool to see. I wonder about the thermal performance. Titanium is typically used over aluminum in aerospace when relatively high temperatures are experienced, (but not as high as the engine) the leading edge of the wing in supersonic jets for example. Being composed of carbon, would it be susceptible to combustion, like diamonds are? Still, with the density of styrofoam, you could certainly replace aluminum in low temperature applications too!
If the structure is highly regular that makes me guess they would have good creep performance, although that’s probably hard to test on such a small sample. It’ll be interesting to see if and when the fabrication can be sped up from two days for a pea-sized sample.
When i used inkscape to export an SVG it kept adding a very faint white outline and I couldn’t figure out why.
So download the entire Internet, got it
The US and (some of) its vassal states also happen to be more or less the only majority English speaking countries in the world, and so get to set the meaning of “America” (singular) when used in English.
With that said, the translation reads “the Americas” (plural) which unambiguously refers to the two continents.
Yeah this reads like self soothing. Looking in the mirror in the morning “I am a big boy!”
The crossover point is 30 km/h. At typical road speeds - not just highway speeds - tire noise dominates.
Sandy Loam??? WHO IS SHE
That’s it, it’s horny jail for you. This is an abnormal amount of horny.
Quebec swear words are almost all Catholicism-derived. The Tabernacle, the Host, the Chalice, the Virgin, etc.
The problem with UBI is it won’t come without the power of the people forcing it. And then when that dies down it can just as easily be taken away. If you’ve got a mass movement with that power, why would stop at a bandaid?
Of course, that would never change in the face of changing financial incentives. The world as it is is the world as it ought to be.
I had one professor who could tell almost any calculator model from 30 feet away. Other than him I never had any professor care about the specific model of calculator during an examination.
It’s not so much the force that is important, regardless of if it’s normalized for body size, it’s the pressure that does damage. psi (or Pa in SI) is the appropriate unit.
We needed to get this shit done 10 years ago. Any delay in removing all fossil fuel emissions now is just a matter of how bad we want climate change to get, rather than preventing it. Net zero by 2050 is a fucking eternity away and is a shit goal, and all the projections that get us on track to 1.5 °C of warming have us extensively using carbon capture which is entirely unrealistic.
Existing nuclear plants in France work, they can load follow to some degree, and renewables can make up the difference with minimal energy storage. But at a certain point you have to stop investing in renewables if you have minimal energy storage and your electricity solution is working.
I am going to emphasize that last part: IF you can’t get enough energy storage, and IF your energy mix is fine, you must stop investment in renewable installations. Without enough storage, the baseload+peak paradigm works, you just have to regulate it.
France’s nuclear plants load-follow to some degree, so it’s not just fossil fuels.
It is the quadratic formula. It already is the solution. The problem is any quadratic of the form ax²+bx+c=0
Have people never heard of the quiet game outside of an Australian cartoon?
A few things: nobody needs to know how many feet are in a nautical mile, nor square feet in an acre, and nobody uses stone in the US. 12 inches to a foot would actually be better than 10 for everyday use if all gradations were 12 because you can easily divide by 2, 3, 4, or 6 and it gives you nice round numbers.
And the conversions between US fluid measurements suck, plain and simple.
