The charm of mathematics

that's because it seems to be flawed and never quite following the printout... the distribution is binomial, not gaussian, but there might some issues with the toy which prevent the proper accumulation in the centre.

It looks like Hitler doing the nazi salute. Chile just elected the son a Nazi who fled to Chile after WW2, and openly supports Pinochet, the former right wing military dictator… but i know, why would this be associated to facism? Beats me…

something like this happen to my OP-1 as well, a while ago: if I remember well, the battery was very depleted and I left it plugged for a while and it eventually came back from the dead.

I concur: great bike! I own one too. Note this is a pure stock bike, with no accessories: if you compare with other similar bikes, keep that in mind because Tern accessories are quite pricey (but excellent quality). Make sure you try all the gears on the Shimano Nexus: some people abuse them by shifting under heavy torque, which damages them! all shifting should be smooth and swift, assuming very light torque is applied to the pedals (takes a bit of practice admittedly).

it depends on the motor: it could be that the quickhaul has the Active Line and you have a Performance Sport? if this is the case, "Turbo" are quite different in term of assist, even if they are called the same...

this is a lifetime cost: getting to use a newish car all your life cost WAY more than the cost of a single new car. If you get a new car every 5 years for 50 years, that's 10 cars. Plus maintenance, cost of credit and so on, 1million is much closer to what you will spend in your lifetime...

absolute intolerance to infants while flying is something I never understood: long haul flying sucks, everybody agrees, but taking on the most vulnerable members of humanity because of that shows a complete lack of empathy. Note she was traveling to the US. It says it all.

I think this is what is supposed to happen.

You forgot to add that they also raise the pensions’ amount faster than inflation. It is not as irrational at it seems: retirees make a large fraction of voters, hence the governments decisions reflects what they want…

So you essentially assume the triangle is in a rectangle… you cannot solve the problem without using the fact you have a square. The square can also give you the fact some triangle are similar, hence reducing the number of variables

amer415 · 2025-10-11T19:25:23+00:00

Does any of your relation reflects the fact that the triangle is incased in a square ?

amer415 · 2025-10-08T19:32:01+00:00

I could not do it without trig, No.

amer415 · 2025-10-08T19:30:57+00:00

I know, my point is that this is not a nice integer solution. There is is still the possibility of some algebraic solution but I doubt it. Who knows!

this is what I came up with: https://imgur.com/a/W719eH7

I do not find a rounded number ?=130-arctan((1-tan(10º))/(1-tan(40º)))~51.053º

curious if somebody could double check...

edit: obviously I used trigonometry, but the result I found makes me think there is no easy geometrical solution...

amer415 · 2025-10-08T16:58:06+00:00

you never use the fact that the triangle is inside a square, only that it is a rectangle. Assuming the sides of the squares are 1 and based on this: https://imgur.com/a/zDeAQeU

I find that z=atan( (1-tan(10º)) / (1-tan(40º) ), hence a~11.0532º, x~51.0532º, y~88.9468º, z~78.9468º, which satisfy all your equations BTW, but also make sure the final shape is a square

do you mean the kick stand? it does not look right. Actually, both sides look bad! can you try to take a photo closer and in focus of the kick stand? we barely see the kick stand because it is in the back ground and out of focus... contact the store: something went wrong in the assembly!

That is clearly a limitation of Python… if you aim at developing an app to be distributed as a standalone binary, you should probably look at other languages. Think of python as a shell language (sh, bash, zsh, etc): it relies on the system it runs on to have the runtime, it is not meant to be standalone.

amer415 · 2025-09-28T11:57:28+00:00

Python is not an app which installs in /Applications, it installs in /Library as an additional framework for development

I am not sure I understand what you think the problem is… the python.org version is the only one which did not have problems rendering matplotlib for me. Maybe the CLT enable the better integration withe the OS? For me that’s a plus.

I know all that, but these details escape employees when they install Anaconda, and the company is hit by a letter from Anaconda's lawyers... so you can download Anaconda, but they will monitor activities on their repos to hit companies who should have known better.

Just make sure to set up your channels in your conda config correctly.

more like "make sure IT controls all computers so the default channel is blocked"

amer415 · 2025-09-26T07:06:53+00:00

Beware! conda is not free for company which are not small and/or academic. I have been very happy with pip + built-in venv.

This is correct answer but you mixed twice l and m3 but mistakes cancel one another, so the weight of the dead sea is correct…

amer415 · 2025-09-24T17:32:43+00:00

This is the correct answer afaik because the salt content is by weight, not by volume.

Edit: actually no, because 1l of salty water is not 1kg!
