nothacking,

This is minor one, but annoys me how comnmon this is: light is made out of litle packets of energy called photons.

Here is a good video on the topic: youtube.com/watch?v=SDtAh9IwG-I (Too lazy didn’t watch: Light is an electromagnetc wave and is is not quantized. Only the interactions between atoms and light are quantized)

JoelJ,

I was under the impression that electromagnetic radiation is both a wave and a particle, and it’s known as the “wave particle duality”.

antim0ny,

Similarly, when people talk about electrons “moving through wires” or other conductors. The electrons are not moving, they are passing energy from one atom to the next but the electrons themselves are not moving.

Spandex_Nightmare,

Well they do move, but just incredibly slowly.

…stackexchange.com/…/speed-of-electrons-in-a-wire

davidgro,

In DC they actually are moving, but it’s something like a few millimeters per hour on average

6mementomori,

huh, I thought quantization of light(or energy really) came from Heisenberg’s uncertainty principle

SelfHigh5,

The large percent of traffic accidents that take place within 5 miles of home. Most people only cover a fairly small radius on a day to day basis so it makes sense if there is an accident, it’s close to home and not 80 miles away… just on average of how far how often you drive. Makes it seem like neighbourhoods are more dangerous than highways or something.

6mementomori,

that is actually an interesting way to think about it

substill,

There is a greater than 5% chance that your death will be someone’s fault.

What about the other 5% though?!

substill,

Non-preventable deaths are about 95%.

JackGreenEarth,

If you believe in God, it’s a 100% chance

Every single rapist and murderer was found to have dihydrogen monoxide inside their body at the time they committed their crimes, and your friends and family may be using it recreationally without you knowing

JackGreenEarth,

I don’t think something you need to survive can be called being taken ‘recreationally’.

kenbw2,

Is that world wide or in a specific country?

Each year, Dihydrogen Monoxide is a known causative component in many thousands of deaths and is a major contributor to millions upon millions of dollars in damage to property and the environment. Some of the known perils of Dihydrogen Monoxide are:

Death due to accidental inhalation of DHMO, even in small quantities.

Prolonged exposure to solid DHMO causes severe tissue damage.

Excessive ingestion produces a number of unpleasant though not typically life-threatening side-effects.

DHMO is a major component of acid rain.

Gaseous DHMO can cause severe burns.

Contributes to soil erosion.

Leads to corrosion and oxidation of many metals.

Contamination of electrical systems often causes short-circuits.

Exposure decreases effectiveness of automobile brakes.

Found in biopsies of pre-cancerous tumors and lesions.

Given to vicious dogs involved in recent deadly attacks.

Often associated with killer cyclones in the U.S. Midwest and elsewhere, and in hurricanes including deadly storms in Florida, New Orleans and other areas of the southeastern U.S.

Thermal variations in DHMO are a suspected contributor to the El Nino weather effect.

One of my favorite Brian Regan bits kinda fits, maybe?

“In 1939, Germany invaded Poland. One thing led to another and the United States of America dropped two atomic bombs on the sovereign nation of Japan.”

Every year, traffic congestion wastes billions of gallons of gas.

Firefly7, (edited )
@Firefly7@lemmy.blahaj.zone avatar

explanation, since this one might be more confusing than most:

Traffic congestion does indeed waste gas. However, any place worth driving to is going to have congestion–driving without congestion is easy, fast, and comfortable, so people generally won’t take other options until roads become congested. Thus, congestion actually reduces gas usage overall, because it is only once areas become congested that people stop driving places.

Trying to avoid congestion, on the other hand, usually involves expanding roads, something which increases driving, and makes other forms of transportation less useful/comfortable, thus increasing gas usage overall.

shouldn’t your first post say congestion saves billions of gallons of gas?

Firefly7,
@Firefly7@lemmy.blahaj.zone avatar

no, since the misleadingly-true fact is still that congestion wastes gas - congestion is cars spending gas on going nowhere, so the gas is wasted

Centrifugal force does not exist

lotanis,

“A laughable claim, Mister Bond, perpetuated by overzealous teachers of science. Simply construct Newton’s laws into a rotating system and you will see a centrifugal force term appear as plain as day.” xkcd.com/123/

bobthened,

It does, it’s just called a different thing. Centripetal force is exactly the same thing as what most people assume centrifugal force means.

Cyna,

It doesn’t exist in an inertial frame of reference. In a non-inertial frame it’s a perfectly valid force

jossbo,

Nice try, QI elf!

Lubricate7931,

human and chimp DNA is 98.8 percent the same

unknowing8343,

I don’t know the exact number, but, come on! Look at those guys! They are basically hairy humans with a slightly less complex system of communication.

Lubricate7931,

Yep but the point is the 1.2% represent millions of gene pairs and the ones we share are not always present or expressed in the same way. So just sharing genes doesn’t necessarily mean were the same or they do the same thing.

www.amnh.org/…/dna-comparing-humans-and-chimps

Yeah chimps are one of our very few (very very) distant cousins left. But i think they rip more faces off than us

If you have a complicated health issue or emergency, the legislative branch of government dictates your potential treatment.

(Most reputable practitioners will temper their recommendations based upon the professional risk involved.)

lotanis,

This is maybe true in the US. Don’t forget that people from all over the world are on here.

j4k3,
@j4k3@lemmy.world avatar

Still holds true either way. If the doctor is or is not at great risk of legal consequences, it will greatly impact your care. I have a complicated case with lots of small spinal damage that all adds up to partial disability. All reputable neurosurgeons here spend five minutes reading the radiology summary from a MRI and walk away from anything that is not easy like my case. It is just too much legal liability to take on hard cases. If you live in a region where it is safer for the doctor to treat difficult cases with impunity, you will likely get better, or at least more, care. In the real world, the legal system plays a major role in medical treatments. No one is throwing away or risking their entire career on your case. Skipping context, your healthcare really is determined by Judges either way. Learning this the hard way sucks.
