Imagine a world without algebra. We can hear the sound of school children applauding. What practical use are parametric equations and polynomials, anyway? Even some scholars argue that algebra is the Latin of today, and should be dropped from the mandatory curriculum.
But why stop there? Maybe we should do away with math classes altogether.
An astronomer says he’d be out of work: we can all forget about understanding the origins of the universe, the cycles of the moon and how to communicate with alien life. Also, no math = no cybersecurity + hackers (who have taken math) will have the upper hand.
Also, without mathematics, you’ll laugh < you do now. The Simpsons creator Matt Groening has peppered his animated show with hidden math jokes.
And why mathematics = love.

ENCORE We’ve all had an “oops” moment. Scientists are no exception. Sometimes science stumbles in the steady march of progress. Find out why cold fusion is a premier example why you shouldn’t hold a press conference before publishing your results. Also, how to separate fumbles from faux-science from fraud.
Plus, why ignorance is what really drives the scientific method.
And our Hollywood skeptic poses as a psychic for Dr. Phil, while our Dr. Phil (Plait) investigates the authenticity of a life-bearing meteorite.

After the winds and water of Typhoon Haiyan abated, grief and hunger swept though the Philippines, along with the outbreak of disease. Are monster storms the new normal in a warmer world? Some scientists say yes, and if so, climate change is already producing real effects on human life and health.
A hotter planet will serve up casualties from natural disasters, but also higher rates of asthma, allergies and an increase in mosquito-borne diseases. It is, according to one researcher, the greatest challenge of our time, straining health care efforts worldwide. But could a “medical Marshall Plan” save us?
Also, why the conservative estimates from the U.N.‘s climate change group don’t help people prepare for worst-case scenarios. And, a controversial approach to saving our overburdened planet: a serious limit on population growth.

A computer virus that bombards you with pop-up ads is one thing. A computer virus that shuts down a city’s electric grid is another. Welcome to the new generation of cybercrime. Discover what it will take to protect our power, communication and transportation systems as scientists try to stay ahead of hackers in an ever-escalating game of cat and mouse.
The expert who helped decipher the centrifuge-destroying Stuxnet virus tells us what he thinks is next. Also convenience vs. vulnerability as we connect to the Internet of Everything. And, the journalist who wrote that Google was “making us stupid,” says automation is extracting an even higher toll: we’re losing basic skills. Such as how to fly airplanes.

ENCORE Time keeps on ticking, ticking … and as it does, evolution operates to produce remarkable changes in species. Wings may appear, tails disappear. Sea creatures drag themselves onto the shore and become landlubbers. But it’s not easy to grasp the expansive time scales involved in these transformative feats.
Travel through millennia, back through mega and giga years, for a sense of what can occur over deep time, from the Cambrian Explosion to the age of the dinosaurs to the rise of Homo sapiens.

“Sorry, closed for business.” That sign hung on doors of national laboratories when the US government shut down. What that meant for one Antarctic researcher: her critically important work was left out in the cold.
So just what do we lose when public funds for science fade? The tools for answering big questions about our universe for one, says a NASA scientist … while one of this year’s Nobel Prize winners fears that it is driving our young researchers to pursue their work overseas.
Yet one scientist says public funding isn’t even necessary; privatizing science would be more productive.
Plus, an award-winning public-private research project changes the way we use GPS … and a BBC reporter on the fate of international projects when Americans hang up their lab coats.

It was the most famous invasion that never happened. But Orson Welles’ 1938 “War of the Worlds” broadcast sure sounded convincing as it used news bulletins and eyewitness accounts to describe an existential Martian attack. The public panicked. Or did it? New research says that claims of mass hysteria were overblown.
On the 75th anniversary of the broadcast: How the media manufactured descriptions of a fearful public and why – with our continued fondness for conspiracies – we could be hoodwinked again.
Plus, journalism ethics in the age of social media. Can we tweet “Mars is attacking!” with impunity?
And why we’re obsessed with the Red Planet.

Your brain is made up of cells. Each one does its own, cell thing. But remarkable behavior emerges when lots of them join up in the grey matter club. You are a conscious being – a single neuron isn’t.
Find out about the counter-intuitive process known as emergence – when simple stuff develops complex forms and complex behavior – and all without a blueprint.
Plus self-organization in the natural world, and how Darwinian evolution can be speeded up.

Discovering bacteria on Mars would be big news. But nothing would scratch our alien itch like making contact with intelligent life. Hear why one man is impatient for the discovery, and also about the new tools that may speed up the “eureka” moment. One novel telescope may help us find E.T. at home, by detecting the heat of his cities.
Also, the father of modern SETI research and how decoding the squeals of dolphins could teach us how to communicate with aliens.

Let there be light! Well, it’s easy to do: just flip a switch. But it took more than the invention of the light bulb to make that possible. It required new technology for the distribution of electricity. And that came, not so much from Thomas Edison, but from a Serbian genius named Nikola Tesla.
Hear his story plus ideas on what might be the breakthrough energy innovations of the future. Perhaps hydrogen-fueled cars, nuclear fusion electrical generators or even orbiting solar cells?
Plus, a reminder of cutting-edge technology back in Napoleon’s day: lighthouses.

You can’t see it, but it’s there, whether an atom, a gravity wave, or the bottom of the ocean … but we have technology that allows us to detect what eludes our sight. When we do, whole worlds open up.
Without telescopes, asteroids become visible only three seconds before they slam into the Earth. Find out how we track them long before that happens. Also, could pulsars help us detect the gravity waves that Einstein’s theory predicts?
Plus, why string theory and parallel universes may remain just interesting ideas … the story of the woman who mapped the ocean floor … and why the disappearance of honeybees may change what you eat.

Imagine: Your pint-sized pup is descended from a line of predatory wolves. We have purposefully bred a new species – dogs – to live in harmony with us. But interactions between species, known as co-evolution, happen all the time, even without deliberate intervention. And it’s frequently a boon to survival: Without the symbiotic relationship we have with bugs in our gut, one that’s evolved with time, we wouldn’t exist.
Discover the Bogart-and-Bacall-like relationships between bacteria and humans, and what we learn by seeing genes mutate in the lab, real time. Also, the dog-eat-dog debate about when canines were first domesticated, and how agriculture, hip-hop music, and technology can alter our DNA (eventually).
Plus, why some of the fastest humans in history have hailed from one small area of a small Caribbean island. Is there a gene for that?

ENCORE Let there be light. Otherwise we couldn’t watch a sunset or YouTube. Yet what your eye sees is but a narrow band in the electromagnetic spectrum. Shorten those light waves and you get invisible gamma radiation. Lengthen them and tune into a radio broadcast.
Discover what’s revealed about our universe as you travel along the electromagnetic spectrum. There’s the long of it: an ambitious goal to construct the world’s largest radio telescope array … and the short: a telescope that images high-energy gamma rays from black holes.
Also, the structure of the universe as seen through X-ray eyes and a physicist sings the praises of infrared light. Literally.
And, while gravity waves are not in the electromagnetic club, these ripples in spacetime could explain some of the biggest mysteries of the cosmos. But first, we have to catch them!

Hi ho, hi ho… it’s out with work we go! As you relax this holiday weekend, step into our labor-atory and imagine a world with no work allowed. Soft robots help us with tasks at home and at the office, while driverless cars allow us to catch ZZZZs in the front seat.
Plus, the Internet of Everything interconnects all your devices, from your toaster to your roaster to … you. So there’s no need to ever get off the couch. But is a machine-ruled world a true utopia?
And, the invention that got us into our 24/7 rat race: Edison’s electric light.
