3g for less than a second is really not to that much. Most people can easily withstand 3g sustained for minutes with (almost) no preparation. Just don't forget to breathe and maybe contract your leg muscles a bit. Many can go up to 7g sustained with half a day of training.
I think back in the day it was recommended to have at least 5 liters per adult triops. My tank was around 100l and I usually had at least a handful of them. Always females only; the males somehow never made it. They would only get eaten by their peers once they died of other causes. Maybe yours were lacking some protein in their diet?
First time I hear of anybody keeping Hydrae as pets.
Well, 0th order approximations are fine if the gradient is indeed about zero for all intents and purposes. It's just very much not the case for exponential functions.
Maybe your analogy could work if you want to say that exponential growth might feel like linear growth locally?
The whole point of exp(t) is that the derivative at t is equal to the value at t. Thus if y_approx = 1 then the derivative is also 1 and not 0 (i.e. constant).
If you're exponentially growing, but currently it's approximately constant, then you're at t = -inf and you'll probably be dead by the time you achieve something significant.
There's this super over-engineered fully automatic fish elevator to go up a 20m tall weir [1] (pdf and German warning). Interestingly, there is no safe way for the fish to go back down, yet.
It's not the object's mass that you care about, but its ballistic coefficient [1]. An object which is very heavy, but also very big, will deorbit just as quickly.
In my experience, the old-school electronics companies believe "if you can't stick a label on it, you can't sell it". In their eyes software is a necessary evil, but it only costs money and doesn't generate any revenue. This is obviously wrong, as the products are worthless without the software and would probably sell better with better software. If they recognized the value of the software then they would probably pay their software engineers better.
For injection molded parts you could start by paying a local consulting firm that specializes in mechanical design to take a look at your part. They will probably be able to help you find a manufacturer and your design will have to be verified by somebody who does this for a living one way or another if you want it to work after a reasonable amount of iterations (better not forget those draft angles). You could also directly ask a local manufacturer of injected parts, as they will have engineers that can help you, but they might only want big customers. Also, that might close doors if you want to move production overseas.
Depending on the size and complexity of your part might just make it for $15k to get the tooling done. The manufacturing itself most probably will never make sense to do inhouse.
I used to work with small fixed wing drones [1] and had birds of prey remove the battery pack from the aircraft while in flight. I always wondered whether they knew or if they just instinctively went for the "head" of the plane and got lucky that the battery was right there.
There were also reports from customers in Australia where eagles would just shred the drone to pieces almost every flight. Putting big googly eyes stickers on the wings seemed to help to some degree.
Could be a neoboletus luridiformis with an unusually slim stem. In any case, I would say the color saturation in this picture is cranked up quite a bit.
