The Mandelbulb (the 3d video) is pretty, but I've always thought that it was a bit of a cheat. The Mandelbrot set equation is almost the simplest equation you could write down. It's easy to remember. The complex structure is locked away in a small equation, and I like that. It's efficient. The Mandelbulb equation is much bigger and, I dunno, it just seems a bit cheaty. Looks great though.
If you think of rotation in turns, do you also only have one cup and use that when cooking? Ie 1 cup of ingredient A + 2 cups of ingredient B always works irrespective of the size of the cup.
I suppose so, but I would imagine that there are different units for whisky, whiskey and whiskey (depending on whether it's Irish or US). There again, US pints are different to our pints. Our pints are better. Cooking? That's far too practical for me. But, yes, that's a good example. Units don't matter provided you're consistent. Although radians are usually missed out by engineersin their units (e.g. angular momentum is often stated as kg m/s^2 not kg m radians /s^2)[1]. A complex issue indeed. [1] I think that's right.
In cooking you have cup measurements, again english & american are different. British cups 250mls (10.00 fl oz) & US cups are 240mls (8.1 fl. oz) .
A tea cup should hold 6 fl.oz But, not all tea cups are equal. And a mug is usually 10-12 fl.oz, but this also can vary.
"Goodbye to pi"? If you want τ, if it's more convenient for you to use it then go ahead, use it. Surely it would be rather fickle of you to say "goodbye" to π? On second thoughts, I do prefer the new piece of π on countdown compared to her predecessor. Given the choice tho, I'd gladly take either.
Internationally there are even bigger variations. Personally I use Le Creuset ramekins which are 0.2L so about a cup when slightly heaped. But a cup is an inherently vague measure for dry foods anyway. Eg the mass of a cup of chopped onion will vary according to how finely it is chopped.
I’m still learning to use my iPad. How do I type in symbols for “pi” and “tau” etc. Is there something like Character Map?
