For most cars driving through air, at sea level, on planet Earth, at normal speed, the drag force F is proportional to the square of the speed (v^2).
That's not exponential because the speed (v) is not in the exponent. In fact, it's quadratic.
Corollaries: The power required to push the car at speed v will be proportional to Fv ~ v^3. The gas spent over time t ~ energy spent ~ power time ~ v^3 * time.
One of my favourite reads from this past year was Infinite Powers: How Calculus Reveals the Secrets of the Universe by Steven Strogatz. It's a wonderful review of the history of calculus, including intuitive explanations of the basics.
I made a poster showing how one might write a Hello World program in 39 different programming languages, and even different versions of some common languages like Java:
I believe that is a C-ism, where the C runtime calls your main() and exits the process with the return value. The Java equivalent is System.exit(int status).
Cool poster! If you don't mind me asking, would you share what tools you use to create this poster? You've got syntax highlighting going on there too. What did you use for that?
Sure, they could have taken a bit more, like proper AOT instead of it being a feature only available in third party commercial JDKs, or some low level niceties like C#.
I would look to the UCSD p-System as a precedent to the JVM. Both are byte-code interpreted VMs. Gosling used the p-system earlier in his career, prior to joining Sun.
Essential oils from plants (terpenes/terpenoids) are hydrogen-rich hydrocarbons and they smell nice. Menthol is an example, with a hydrogen mass fraction of about 12%. For comparison, water has a hydrogen mass fraction of about 11.2%.
If you abandon the "smell nice" constraint, you can get an even higher hydrogen mass fraction. For example, n-pentane has a hydrogen mass fraction of about 16.8% and it's liquid at a pressure of 1 atmosphere and a temperature of 25 degrees Celsius, but it evaporates rapidly, so you need to keep it in a container.
If you don't mind pressurizing the container a bit, you could put ammonia in there, and it has a hydrogen mass fraction of about 17.6%.
Yes, because hydrogen atoms are so light. It takes 12 hydrogen atoms to equal the mass of a carbon atom and 16 hydrogen atoms to equal the mass of an oxygen atom.
Some people actually think it does. Especially before it had so much ethanol added. I don't think it smells particularly nice but it is definitely a memory trigger of being a small kid helping my dad get the lawn mower ready to cut the grass.
My main learning is that character.ai is consistently in the top four, along with ChatGPT (always #1) and Claude. I didn't even know it was in the running.
No, you're thinking of the term "cattle". Calves are indeed cattle. But "cow" has a specific definition - it refers to fully-grown female cattle. And the male form is "bull".
Because managing cows is different than managing cattle. The number of bulls kept is small, and they often have to be segregated.
All calves drink milk, at least until they're taken from their milk cow parents. Not a lot of male calves live long enough to be called a bull.
'Cattle' is mostly used as an adjective to describe the humans who manage mostly cows, from farm to plate or clothing. We don't even call it cattle shit. It's cow shit.
My brain said "y" and then I caught myself. Well done!
(I suppose my context was primed both by your brain-teaser, and also the fact that we've been talking about these sorts of things. If you'd said this to me out of the blue, I probably would have spelled out all of "yolk" and thought it was correct.)
No one who knows anything about cattle does, but that leaves out a lot of people these days. Polls have found people who think chocolate milk comes from brown cows, and I've heard people say they've successfully gone "cow tipping," so there's a lot of cluelessness out there.
> Many people use cow to mean all bovines, even if technically not correct.
Come on now :0
I just complained non-natives would have a problem distinguishing between a cow and a calf, and you had to bring those bovines.
To make it easier, would just drop that in my native language, the correct term for bovine is more used to describe people with certain character, that animal kind.
