Hey all. Looks like my 15 year anniversary of joining PF happened yesterday (while my internet was down). Just wanted to say thanks to everyone, staff and non-staff, for helping make PF such a wonderful community over the years. Here's to everyone at PF, current, past, or future. Cheers!

Got some 6 ft ramps from a local store. Works perfect.

Thanks all!

I haven't really started to look yet, as I didn't know how long they needed to be.

Hey all. I'm looking to buy a zero-turn mower and I need to build/purchase a ramp to get it into my shed for storage. Exact model is this one. I need to figure out how long of a ramp I need to make sure the mower doesn't bottom out when driving up and down the ramp. Mower stats: Wheelbase...

If you spill a bunch of batteries into a stream, are the volts flowing now?

I believe the 'speed' is referring to the FPS of the camera.

Don't worry. It's filled with foam pellets so it doesn't hurt when it hits you. :wink:

Nice!

I wonder if a rotating neutron star would emit much RF radiation if its magnetic poles coincide with its physical poles. @Ken G any idea?

I'm not sure what to tell you that hasn't already been said. You cannot use the motion of the bike to charge the same battery you are using to power the bike, except during regenerative braking.

I don't know what you're trying to say with this.

Let's say the battery outputs 100 watts to the circuit that includes the generator. The generator will receive 95ish watts thanks to losses in the battery and the rest of the circuit. Then the generator will output 90ish watts, again due to various losses (resistance, radiative losses, etc)...

Nice. I'm bald, so now I have an excuse to go inside instead of mow my yard. "My brain is too hot because I don't have hair to cool it down, Honey!!"

It's fundamentally flawed, as such a model doesn't match our observations about the current and past state of the universe. As PeroK said, take a deeper look into what we know about the BBT and how we know it and you'll see why we model the big bang the way we do. Thread locked, since personal...
