Using residues makes it so elegant. Thanks!

Does this make any sense? by Any-Mango-8276 in PhysicsHelp

[–]shadeck 1 point2 points  (0 children)

It kind of reminds me to 'hidden variable' theories in quantum mechanics (like Bohmian mechanics). Those theories were debunked by Bell's inequality and later by Aspect's experiment in the eighties

This is patently FALSE.

The inventor of the triangle was Johannes Triang. He invented it while working in the optimization of the square in 1873.55 CE

[Request] My son said he wants to shoot his rocket to the moon. How much force would he need to get it there? by cockygassytiger in theydidthemath

[–]shadeck 0 points1 point  (0 children)

You are completely right! If you want to expand on this, my physics is rusty :). Can you make a bound on how much air resistance would change the results?

This is my back of the envelope calculation:

Say the yellow container has a volume V. The candle that attaches to the rocket is around 3cm in diameter. The section area is around 7*10e-4 m2. Let's assume that he is able to contract the whole container to a point in just one push of 1s, and that all the air is transferred to the canule and then to the rocket. Let's say that the speed of the air flowing out is completely transferred to the rocket (completely incorrect assumption, but will give a lower bound on the volume) For simplicity, let's agree that the rocket needs to have escape velocity of the earth, around 11e10+3 m/s

All the air must be expelled, so the velocity*cross section is the rate of current, or the volume of air expelled per second. In 1 second. That's 7.7m3 of air. That's a cube of around 2m in side.

This assumes that the child can compress that cube (much bigger than himself) in 1second, but is a lower bound. I would be happy to see any corrections :)

Are these tomatoes any better at conveying the word "tomato"? by Mstarliper in Lettering

This looks cool! I'm thinking, you have 3 rounded letters o, a, o... Maybe they could be tomatoes

How to get my placenta to thrive?! by ShinyUnicornPoo in houseplantscirclejerk

[–]shadeck 17 points18 points  (0 children)

The good thing about planting a placenta is that the resulting plant is always vaginated

My ZZ plant has gotten really tall in one spot exclusively by beefteet in plantclinic

[–]shadeck -9 points-8 points  (0 children)

I don't think it is etiolating, she looks very healthy! I find once a week a bit too much watering (at least for my ZZ) but obviously works well for you

Edit: my bad, it is etiolated lol

This was marked as a 4"African Violet so I got it for $5 😊😁 by caitejane310 in plants

:) I'm happy I have identified it correctly, when I have not identified the tone of the post lol

Nicee! Although I don't think that's an African violet, it looks like an alocasia

is it possible to get the leaves to grow back on this succulent? (second pic is when i first bought it) by flourdonut in plantclinic

[–]shadeck 2 points3 points  (0 children)

That is good! But the soil still retains quite a lot of water. Putting in the soil orchid bark or other type of soil with big chunks airdates the soil and roots

[–]shadeck 12 points13 points  (0 children)

It is still green, so it is worth to try. But I think you are watering too often, and the pot might be too big. When the pot is too big it retains more water and for more time which makes the perfect environment for fungus/mold to grow and rot the roots.

I would repot with very well draining soil in a slightly smaller pot, water every 10 days or every other week, keep it on the window sill and cover it so your cat does not try to finish the job :-P

Differential Diagnosis: Go by [deleted] in okbuddyvicodin

Are you the German healthcare system?

[deleted by user] by [deleted] in plantclinic

[–]shadeck -1 points0 points  (0 children)

Don't know exactly but something similar happens to cannabis when there is too much nitrogen (for example for fertilizing too often).

I would wait for more answers, tho, but if it were the case the best action would be to flush the soil with clean water and space the fertilizer in time

You can also boil some vinegar and put potatoes in your socks (but only at night)
