What’s your favorite interesting fact?


@taetaetoofs@lemmy.world was talking about tornadoes and it was really interesting, figured I’d see what other cool things we all know

When projecting a movie, presentation or whatever onto a canvas, anything you see as black (text, etc) is just the pure plain white without light shining on it.

Turn the projector off and the parts that looked black a second ago now look chalk white with no changes done to that part.

Would that be in number of tires only or in volume too?

@taladar @Jeraxus It's a Guinness World Record for number of tires per year (ongoing record holder), in volume they don't remotely compete.

If you split the connection between the left and right brain hemispheres as has been done to some people suffering from seizures you can then by using clever methods interview each side separate from the other and discover that they do not agree about most things.

What's ever more interesting is that you can give tasks to one side and let the other side observe you do these tasks and when questioned it will come up with lies about why it did this despite this not being the actual reason.

Split brain experiments if you want to google more info.

@shootwhatsmyname Two parts, the easier to chew is that Microphones are basically just speakers wired backwards.

The second part is Solar Panels are basically just LEDs wired backwards.

(In both cases there's a lot of design work around them to make them better at one task than the other, but the technology is still the same)

And electric generators are electric motors wired backwards.

@Murdoc Oh yeah! And that's how "regenerative braking" works!

That depressingly makes a lot of sense
in reply to Yewb

There's one, but use isn't widespread enough to be useful in most cases.
in reply to Yewb

same thing with gold.

we dont actually know how much gold has been mined and audits have a very wide margin of error.

SQL injection is what Anonymous used to steal, yes, but there are also other attacks that can be done

In 1990 British Airways 5390 suffered an explosive decompression when a cockpit window blew out due to improper maintenance. The force of the decompression partially pulled the captain out the window pinning him to the fuselage while his feet were caught on the control column. Thanks to the efforts of the first officer and flight attendants the plane was able to land safely around twenty minutes later. There were no fatalities.

73% of all bathroom accidents happen outside of a bathroom.

96.4% of all statistics are made up.

Most electric cars only have 1 gear and it's always engaged. If you put the car in reverse, it uses the same gear, but the motor spins the other way.

Even in neutral the motor still spins when the wheels are turned, it just doesn't output any power to the wheels.

There's a certain subset of reality that is non-physical and timeless, called "ideas".

Look on the internet for "Platon ideas" to find out more.
