Putting Einstein first: It’s time to stop lying to our children about physics

by David Blair for Ockham’s Razor, ABC Science

Isaac Newton is a physics icon, but he was wrong.

Sure, three hundred years ago, his discoveries about gravity and the laws governing motion revolutionised the world.

And yes, sure, those discoveries led to an incredibly useful mechanistic, deterministic view of the universe – in which one thing causes another.

It’s the story we all still learn in school. But Einstein proved it was wrong a century ago. Continue reading Putting Einstein first: It’s time to stop lying to our children about physics

Why Physics Says You Can Never Actually Touch Anything

by Jaime Trosper, Futurism

If you needed proof that physics is really strange…

If you’re reading this right now, it’s a sure bet that you are touching something, be it your cellphone, laptop, chair, desk, or a nice plush bed with Egyptian-cotton sheets (we can dream, right?). Speaking of that nice plush, comfy bed, I hate to shatter the illusion, but you aren’t actually touching it.

Most massive neutron star ever detected strains the limits of physics

by Ashley Strickland, CNN

Astronomers have detected the most massive neutron star ever, and it almost shouldn’t even exist.

Neutron stars are the smallest in the universe, with a diameter comparable to the size of a city like Chicago or Atlanta. They are the leftover remnants of supernovae. But they are incredibly dense, with masses bigger than that of our sun. So think of the sun, compressed into a major city.

Physics explains why time passes faster as you age

by Ephrat Livni, Quartz

Mind time and clock time are two totally different things. They flow at varying rates.

The chronological passage of the hours, days, and years on clocks and calendars is a steady, measurable phenomenon. Yet our perception of time shifts constantly, depending on the activities we’re engaged in, our age, and even how much rest we get. An upcoming paper in the journal European Review by Duke University mechanical engineering professor Adrian Bejan, explains the physics behind changing senses of time and reveals why the years seem to fly by the older we get.  (The paper, sent to Quartz by its author, has been peer-reviewed, edited, and has been approved for publication but a date has not yet been set.)

Scientists Just Melted a Solid Below Its Freezing Point

by Ryan F. Mandelbaum, Gizmodo

Imagine you are standing in a freezer.

You look at an ice cube. “Ah, a solid, yes, this makes a lot of sense to me,” you think. But suddenly, it begins to melt. “Did someone turn up the temperature?” No. The laws of physics you remember from high school tell you this is impossible. You lose your goddamned mind.
