Wayfaring: do you want to go ahead and get your flu shot today?
Patient: no, I don’t get them. I’m not against vaccines, just the flu shot.
Wayfaring: why is that?
Patient: I’m just not comfortable with all the bad stuff they put in it.
Wayfaring: ok well let’s talk about it. What substances in particular worry you?
Patient: oh uhhh… you know… the bad ones.

While physics can show us amazing things about our universe, it doesn’t always agree with how we think things should work. Sometimes, physics can be very counter-intuitive, and often unsettling. So, here’s my list of physics facts that can be a bit unnerving.
10: Weight doesn’t matter
If it wasn’t for air resistance, everything would fall at exactly the same speed. If you let go of a hammer and a feather from the same height at the same time on the Moon, they would hit the ground simultaneously.
9: Gyroscopic precession
It doesn’t matter how much you know about physics; gyroscopes are weird. The way they seem to defy gravity makes you rethink everything you know about physics, despite being fairly simple toys. Still, it’s all just Newton’s laws of motion.
8: Neutrinos and dark matter
We like to think that we can interact with most of the world around us, but this couldn’t be further from the truth. Neutrinos and dark matter are passing through your body right now, as if you weren’t even there. The fact that 65 billion neutrinos pass through each square centimeter of your body every second is weird enough, who knows what we’ll learn about dark matter.
7: Photons are particles
Light travels like a wave, but can only interact like a particle. It can interfere and have a frequency, but it can only take and give energy in discrete quantities. It behaves like nothing else in our macroscopic world, and can be very difficult to imagine.
6: Electrons are waves
We’ve established how photons act like waves and particles, but surely massive particles act normally. Nope! Even electrons have wave-like properties. In fact, everything acts like a wave! Except these waves come in discrete quantities, which we’ll call particles. This won’t get confusing.
5: E=mc^2
Einstein’s most famous contribution to physics states that matter is simply another form of energy, which has very profound consequences. A wound-up Jack-in-a-box would weigh ever so slightly more than a released Jack-in-a-box, due to the potential energy stored within.
4: Time is relative
The core of special relativity states that time passes differently for different observers. If you took a trip to Alpha Centauri at 99% the speed of light, everyone on Earth would see the trip take 4.4 years, while you would only experience 7.5 months. Time travel is real!
3: The (not so empty) vacuum
Something can be created from nothing, as long as it goes right back to being nothing quickly. In seemingly empty space, particles pop in and out of existence all the time as a result of the uncertainty principle. Not to mention, space is inflating at an accelerated rate due to “dark energy”. To the vacuum, the law of conservation of energy is more of a suggestion.
2: c is the fastest speed
Another important point in special relativity is that nothing could ever go faster than light. This doesn’t sit well with a lot of people, but the math doesn’t lie. To even get something with mass to travel at the speed of light would require infinite energy. Even if you somehow get around this, there are just too many mathematical problems with superluminal travel. Like it or not, the universe has a speed limit.
1: The cat is dead and alive
How could it not be this? The nature of quantum mechanics allows for objects to take on two seemingly contradictory states in a ‘superposition’. An electron can be in two places at once, or in a more extreme example, a cat can be both dead and alive. Of course, this weird property goes away once someone makes an observation. It’s as if there are tiny physics trolls messing with nature whenever we’re not looking.
Of course, there’s plenty more unsettling physics facts, like the space-bending nature of general relativity, or the “spooky action at a distance” that is quantum entanglement, but these are my top 10. I’d like to hear any unsettling physics facts you think I’ve missed, though!
do tumbleweeds actually blow around in the southwest or is that a myth…?
All the vanco
Isn’t it funny how on TV : 1) getting shot in the shoulder is always treated like it’s a minor flesh wound. It’s not like you’ve probably sustained serious or even permanent damage to your arm, or even gone through your lung…nope. 2) People are always dying of some vague infectious disease that’s only hinted at. I mean, it’s probably TB, but still, it’d be nice to get some closure. 3) People catching something after a walk in the rain and then dying. 4) Cardiac arrest is like, totally NBD. A couple of (really badly performed) pumps on the chest, and the victim is up and talking as if they didn’t just drop dead. Like, if you’ve really just arrested, you’ve probably got 5 broken ribs, an ET tube in your throat and you’ve just earned yourself a ticket to ITU.
The Björketorp Runestone is one of many standing stones (menhir) located in Bleking, Sweden and is one of the world’s tallest runestones, measuring 13.7 feet (4.2 m) high. It is part of a stone circle with two other blank standing stones, with several other solitary stones in the surrounding regions. Most scholars date the runestone’s inscription to the 7th century AD. It’s carved with a type of runes that form an intermediate version between the Elder Futhark and the Younger Futhark. The runestone is inscribed on both sides, the shorter message appears to say “I foresee perdition” or “prediction of perdition” and the longer side’s inscription (pictured) translates as:
“I, master of the runes(?) conceal here runes of power. Incessantly (plagued by) maleficence, (doomed to) insidious death (is) he who breaks this (monument). I prophesy destruction / prophecy of destruction.”
Local lore says that the curse came true at one point. Long ago, a man wanted to move the runestone so that he could have more room to farm, so he piled wood around it to attempt to heat the stone and then crack it with water. The weather was calm with no wind at the time, but as soon as he lit the fire a sudden gust came and lit the man’s hair aflame. He dropped to the ground to put it out but his clothes caught fire and the poor man died in agony. The flame around the runestone, however, was miraculously extinguished, as if someone had smothered the fire.
Most animals with a well-known white morph (lions, tigers, domestic cats, peacocks) are leucistic, not albinistic. True albinos are much rarer and are usually only bred-for in indoor pets (mice, rats, snakes).
