Thermodynamics – The Conversation

Scientists are trying to figure out if time travel is even theoretically possible. If it is, it looks like it would take a whole lot more knowledge and resources than humans have now to do it.

A wireless transmitter uses almost no power and at first glance appears to violate the laws of physics. It’s actually a clever use of physics that could one day transmit data from tiny remote sensors.

Like a coffee you can’t finish stirring, a ‘time crystal’ is a strange quantum state of matter than never settles down to equilibrium.

Theories exploring the possibility of time travel rely on the existence of types of matter and energy that we do not understand yet.

Winter jackets may seem simple, but sophisticated engineering allows them to keep body heat locked in, while staying breathable enough to let out sweat.

Freezers use a evaporation and condensation to pump heat out of the fridge and into the kitchen.

Getting tellurium and phosphorus to form a molecule is stupidly hard and not very glamorous. Here’s why it’s worth the effort.

Major airports around the world will see more frequent flight restrictions in the coming decades because of increasingly common hot temperatures.

In Beijing’s climate, you could coat a Sydney apartment in a few inches of snow with the same energy the air conditioning would use in an hour.

When you’re running late in the winter, you don’t want to have to spend time scraping frost off your windshield. Try some expert-recommended techniques instead.

Emptying and refilling a battery is a lot like pouring water from one glass to another, over and over again.

This is a really important question, and one which climatologists work on in many aspects of their jobs.

2024 marks the bicentenary of William Thomson, aka Lord Kelvin, arguably the most influential scientist of the 19th century and perhaps beyond.

For those drawn both to engineering and a seafaring life, marine engineering and nautical science are ideal careers.
