How To Get the Most Out of Your Smartphone Battery

There is good news, which is the lithium-ion batteries inside today's phones are more reliable, longer-lasting, and safer—well, mostly —than ever before.But lithium-ion batteries definitely prefer a slow and steady input.

Rare weather phenomenon possible

Rare weather phenomenon possible

Called a Sudden Stratospheric Warming (SSW), it occurs when the temperature of the stratosphere (30-50km above ground) over the South Pole rises by more than 25ᵒC.The Southern Hemisphere is characterised by a cold Antarctic continent surrounded by relatively warm seas.

Headed to Mars? Pack Some Aerogel—You Know, for Terraforming

Headed to Mars? Pack Some Aerogel—You Know, for Terraforming

It’s called a solid-state greenhouse effect—light penetrates the surface, passes through the translucent ice, and then hits darker regolith, which warms up. Could an insulating material create a solid-state greenhouse effect warm enough to make Mars habitable?

Should You Wear White or Black on Hot Days? Here's the Data

Should You Wear White or Black on Hot Days? Here's the Data

Perhaps the question should be: Does white reflect MORE thermal radiation than black clothing (I'm equating thermal radiation and infrared light—same thing). The T-shirts (both the black and the white) have an emissivity very close to 1—they don't really reflect much infrared radiation.

Simple Experiments Show How Motion Is Equivalent to Heat

The change in thermal energy of an object depends on three things: the object's mass, the change in temperature, and the specific heat capacity (which depends on the material). In order to calculate the change in thermal energy, I need the specific heat capacity for the two materials (water and copper).
