If you work in an office, chances are you or the person sitting next to you has grumbled about it being too hot or cold. No one likes rugging up on a summer’s day to contend with the air-conditioning. Or having to shed one too many layers in winter to compensate for stifling heat indoors.
This eerie picture shows an Antarctic research station which is used to store, of all things, snow samples. But with temperatures regularly dropping below –70°C, there’s no need for refrigeration.
Few things will earn you a nastier, contemptuous snarl from a Very Serious Scientist than using that lowly, scum-based Fahrenheit scale for measuring air temperature. "Celsius is the proper form of measurement," they haughtily trumpet, "because everyone else uses it." Everyone else is wrong.
Last week, NASA and NOAA announced that 2014 was the hottest year in Earth's recorded history. This animation by Bloomberg brings that finding into sharp focus.
What if your dining room table could show you when your coffee or cocoa is too hot to drink? That could be a reality today: hacker Ken Kawamoto shows us how with a technique called thermal projection mapping.
The fire hydrant that we know today traces its origins back to fire plugs. Water mains that transported fresh water in a city or town used to be made of hollowed out logs buried beneath the streets. Whenever there was a fire and firefighters needed water, they dug up the cobblestone street and drilled a hole into the…
The sound of summer is ice cracking as you pour yourself a cold drink. Hearing that snap and pop cools everybody down. But why does ice crack? Periodic Videos explains the reason why ice straight from freezer suffers that sudden crack versus how ice left on a tray will just melt instead of crack.
A team of researchers has made the world's most sensitive thermometer at room temperature, which is three times more precise than any to go before it—and it's made of light.
With Minute Physics videos we pretty much expect to have the universe explained to us in . . . a minute. Or maybe a few minutes. But this rundown of temperature and how to achieve "negative temperature" only takes 10 seconds. Impressive.
Just like "close door" elevator buttons and press-to-walk street signs, hotel thermostats are a notorious public placebo. You see the rig on the wall and get to feel like you have some modicum of control, but in reality, that thermostat will only let you go to 72, maybe 70 if you're lucky. But after that, it's…
A team of scientists has created a material that's enough to confuse fellow researchers and the Predator alike: a substance which looks cold when viewed using infrared light even when it's getting hotter.
News alert! The world is going to get hotter. NASA combined dozens of climate models from around the world to estimate temperature and precipitation patterns for the next 87 years. That'll get us right to the year 2100.
On Friday the UN Intergovernmental Panel on Climate Change put its collective foot down about global warming. It's happening and it's our fault. But as with any issue that affects all of humanity, the most important question is what's gonna happen to you? Will you have to give up air conditioning? Will the song "White…
The Intergovernmental Panel on Climate Change has this morning a landmark report which places the blame for climate change squarely at the feet of humankind.
This glowing purple cloud may look stunning, but you wouldn't want to get too close—because it's actually a multi-million degree celsius gas cluster.
Turns out diamonds have powers beyond bringing bling-happy jewelry enthusiasts and hopeful lovers to their knees. Harvard researchers have figured out how to make the shiny little pebbles into the world's tiniest thermometers. How tiny? Small enough to take the temperature of an individual cell.
It's summer. It's stinking hot. And for any silly person who leaves their pets (or any imbecile who leaves their kids) inside a parked car, watch this video where a doctor traps himself inside a parked car to see how how it gets. Even with all four windows cracked down a bit, the car temperature reaches 117 degrees…
If you compare the feeling of touching a piece of metal versus a piece of paper, the metal will always seem cooler, even if both objects are actually the same temperature. So what gives? It turns out that what we're really feeling as cold when we touch something is actually an object's increased ability to conduct…
