Every magnet has two sides: a north pole and a south pole.
The energy needed to pull magnets apart comes from you, and you get it from the food you eat. And the plants or animals you eat get their energy from other plants and animals, or from the Sun. All energy comes from somewhere.
Women are still typically the minority on academic hiring committees in science, and “majority rules.”
The award of a Nobel Prize in physics to Donna Strickland is an opportunity to build support for women in science, says one female physics professor.
Recognition: The University of Waterloo’s associate physics professor Donna Strickland after being awarded the 2018 Nobel Prize for Physics.
Donna Strickland is the first woman in 55 years to be awarded the Nobel Prize in Physics. Let's hope the next such award to a woman won't take so long.
Using lasers to trap and move particles changed the way we're able to study microscopic life.
Swings can be educational tools.
The way science is currently taught in southern African countries ignores the fact that the whole environment is a laboratory for learning.
We need female role models in the NSW physics syllabus to normalise women in physics and encourage their engagement and further study.
The new physics syllabus for year 11 and 12 students in NSW contains no mention of specific women who have contributed to the field, nor their work.

Astronomers are voting to rename one of the laws of physics. The voting may have far-reaching effects leading to renaming of other laws and giving 'forgotten' scientists due credit.
What goes up, must come down.
It's not just Earth: everything in the universe has it's own pull because of gravity – even you. Here's how it works.
Machine learning is changing the world in ways that we are just beginning to appreciate. But could it change the way we do science and the reasons why we do science?
Jumping in elevators is fun. If you like jumping.

If you fall one storey, dust yourself off – you'll be fine. If you fall seven storeys: sorry, but you've probably got about 2 seconds to prepare to meet your maker.
Once the car is at steady speed, the insect doesn’t need to be pulled along anymore and it won’t be able to tell that the car is moving.
If the insect wants to stay right in front of your nose, it must fly forwards just a little bit when the car is speeding up. But when the car is at constant speed, it only needs to hover.
In fact, some things are slowing the Earth down or could change its spinning in the future.
To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago.
In 1954, three scientists observed a paradox to which they gave their name: the Fermi-Pasta-Ulam recurrence. Now, fibre optics are on the way to finally providing an explanation.
You may need to pop your ears by yawning when you go up in a plane.
Listen up. Today we're hearing all about why your ears pop when you go up, up, up and away.
After this episode, you’ll be able to explain how quantum mechanics affects everything from the way your jeans are cut to the headphones you use.

Today on Trust me, I'm An Expert, we're explaining the tricky topics: what is quantum mechanics? What does the research say about lone actor terrorism? And why do people like pimple popping videos?
Harrison Ford as Han Solo with his blaster in the old Star Wars triology.
Plasma physics suggests Star Wars blaster guns would be extremely deadly.
How does our world work on a subatomic level?

A particle physicist explains just what this keystone theory includes. After 50 years, it's the best we've got to answer what everything in the universe is made of and how it all holds together.
It’s been 70 years of instant photography, thanks to Edwin Land, on the left.
Whether at a family gathering or in a research lab, getting access to images immediately was a game changer. And Land's innovations went far beyond the instant photo.

A podcast on intuition: from how it works in the body, to how to harness it, and the story of two scientists who followed a hunch – about quantum biology.

Australian scientist Mark Oliphant helped push the development of nuclear weapons during World War II but later riled at US attempts to keep the UK and others out of the nuclear arms race.
