A Black Lady Sketch Show Is a Much-Needed Jolt to TV Comedy

In fact, the foursome are among a rising comedy avant-garde on TV that includes Spanish language curios (HBO's charming Los Espookys ), alt-sketch programs (Netflix's deliriously clever I Think You Should Leave with Tim Robinson and Comedy Central's Alternatino ), black mockumentaries (IFC's Sherman’s Showcase ), and more traditional fare ( South Side , which debuted on Comedy Central last week to impressive numbers).The boom is likely to hold, too.

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.

Collective Fishing Agreements Benefit Both Groundfish and Fishermen

Collective Fishing Agreements Benefit Both Groundfish and Fishermen

Fishermen from Morro Bay, Half Moon Bay, and Fort Bragg formed an initial working group with TNC to explore the formation of a cooperative agreement aimed at reducing bycatch of overfished species and providing benefits to fishermen members, like reduced financial risk and uncertainty.

The Physics of Heating Up Water with a Battery

The Physics of Heating Up Water with a Battery

With that, I can measure the change in temperature of the water to calculate the change in thermal energy and compare that to the energy produced by the battery.

Simple Experiments Show How Motion Is Equivalent to Heat

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).

Legal Scholar Tim Wu Says the US Must Enforce Antitrust Laws

Wu, a law professor at Columbia best known for coining the term "net neutrality," details how presidents of both parties used the Sherman Antitrust Act of 1890, which outlawed monopolistic business practices, to split up the likes of Standard Oil and AT&T, and to block anticompetitive mergers.

How Many Times Do You Have to Slap a Chicken to Cook It?

How Many Times Do You Have to Slap a Chicken to Cook It?

Since I know the heat capacity of water, I can use that decrease in temperature of the water to calculate the increase in thermal energy of the turkey. Conservation of Energy If I assume chicken is similar to turkey, I can calculate the change in thermal energy to cook it.

Why Electric Cars Struggle in the Cold—and How to Help Them

Why Electric Cars Struggle in the Cold—and How to Help Them

“You don’t have as much power when you want to discharge,” says Stefanopoulou, “The situation is even more limited when you want to charge.” Modern cars are designed to take that into account, with battery thermal management systems that warm or cool a battery.

Always Too Hot or Cold? The Embr Wave Is Your Personal Thermostat

Always Too Hot or Cold? The Embr Wave Is Your Personal Thermostat

That's because in cold conditions, the local temperature of your hands and feet dictate how comfortable you feel, says Dr. Hui Zhang, a research scientist at UC Berkeley's Center of the Build Environment.

It’s set to come out later this year, but LG is cagey on the price—likely because it will take more than a fat roll of Franklins to afford it.—Jeffrey Van Camp It's Thermo Time 8:55 am: One of the wearables that stood out at last night's CES press preview was the Matrix PowerWatch 2, the follow-up to Matrix’s original smartwatch.

NASA Will Land InSight on Mars With Cunning—and Lots of Cork

NASA Will Land InSight on Mars With Cunning—and Lots of Cork

On Monday, November 26th, it will attempt its eighth, when it endeavors to land the $830-million InSight spacecraft on Elysium Planitia, a vast plain just north of the Martian equator.If NASA is successful, InSight (short for Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport) will be the first mission to investigate Mars' deep interior with thermal probes and seismometry, an approach scientists think will address questions about the red planet's formation and composition.

Electrofishing Threatens A Rare Dolphin-Human Partnership

Electrofishing Threatens A Rare Dolphin-Human Partnership

But the dolphins that live here in the Ayeyarwaddy River are extremely special — they’ve learned to fish with humans. Naing Lin says that electrofishing is jeopardizing fish populations that both the dolphins and legal fishermen rely on for food.

Ancient civilisation? Was prehistoric global warming caused by pre-human species

Ancient civilisation? Was prehistoric global warming caused by pre-human species

Was prehistoric global warming caused by pre-human speciesA new study from a climatologist and a professor of astrophysics has revealed a massive spike in global warming 56 million years ago.This spike was discovered in a dramatic change in the geological composition buried deep beneath Earth’s surface in an era known as the Paleocene-Eocene Thermal Maximum (PETM).To investigate the idea of a possible pre-historic intelligent civilisation, the duo, Professor Adam Frank, of the University of Rochester and Gavin Schmidt, director of Nasa's Goddard Institute for Space Studies (GISS), examined what evidence we, as humans, would leave behind if we were to become extinct.Writing in The Atlantic, Professor Frank said: “There is a conundrum here.
