So everyone knows the equation e=mc^2, but most people have no idea what it means. So I’m going to explain what Einstein’s (and arguably physics) most famous equation means in plain and simple English. Energy = mass * the speed of light squared

The equation basically displays the idea of mass-energy equivalence. This states that every object has an equivalent proportion of energy to mass, that proportion is equal to the speed of light squared. (Energy/mass=speed of light squared)

This means that the amount of energy (Joules) in a system is equal to the mass of the object*the speed of light*the speed of light. Now we know the speed of light is a huge, huge, huge measurement— now imagine it squared. That means even a really small amount of mass gives off huge amounts of energy.

This simple concept stems off onto multiple complicated concepts such as the fact that we could convert energy to mass (which lead to the discovery of antimatter,) the fact that when stars and other nuclear substances emit energy they are converting their mass into energy, therefore destroying their mass. This equation is simple to understand, and can be applied to so many aspects of physics and gives us a much greater understanding of the workings of our universe.

Lucy in the sky with demons

A few months ago David Chambon has been working on a series of amazing photographs of insects covered in dew drops. If the “creativity” of the phenomenon is due to the nature only, Chambon takes credit for putting in focus, with exemplary photographic expertise, these little natural wonders.

Many researchers believe that physics will not be complete until it can explain not just the behavior of space and time, but where these entities come from.

# How It Works: Inside The Machine That Separates Your Recyclables

1) Tipping floor
Dump trucks deliver mixed recyclables to the facility and pile them on the floor. The driver checks to make sure no oversize objects, such as a car engine, are in the mix.

2) Drum feeder
A mechanical claw grabs a handful of material from the tipping floor and drops it into a spinning drum, which evenly distributes the recyclables onto a conveyor belt.

3) Initial sorters
Workers extract plastic bags, coat hangers, and other items that might jam up the line, as well as anything that won’t fit through the sorter.

4) Large star screens
A series of offset star-shaped discs called star screens—originally invented by the Dutch in the 1950s for sorting tulip bulbs—lift out corrugated cardboard. Smaller items fall through the screens and continue down the conveyor belt.

5) Second sorters
As the material travels away from the star screens, human workers positioned along the line remove smaller contaminants. “This is where we pull out people’s wallets,” says John DeVivo, a co-owner of Willimantic Waste Paper.

6) Medium star screens
Three smaller star screens lift out different grades of paper, which makes up two thirds of recycled material at Willimantic Waste Paper. Plastic, glass, and aluminum fall through the screens and roll back down onto the main belt.

7) Glass sorter
Glass, which is heavier than plastic and aluminum, falls through the star screens and lands in bins below. A separate system of conveyors moves the material to a different area on-site, where it’s ground into a coarse sand for shipment to glass recyclers.

8) Magnetic metal sorter
A 3,900-gauss magnet passes above the conveyor and attracts anything magnetic—usually only 4 percent of the total recyclable material.

9) Eddy current separator
A magnetic field induces electrons in aluminum to create a magnetic field of their own, known as an eddy field. By interacting with the machine’s magnetic field, the eddy field pushes aluminum off the main conveyor onto another one.

10) Infrared lasers
At this point, only plastic remains. Infrared laser beams shine on the plastic items, and a sensor detects the signatures of different grades of plastic. Strategic puffs of air separate the recyclable and nonrecyclable kinds into different bins.

11) Baler
Every 70 seconds, the last machine on the conveyor belt makes a bale of recycled paper, plastic, cardboard, or metal. A single bale of paper is five feet by four feet by three feet and weighs approximately one ton.

12) Landfill
Whatever items are left—jar lids, shoes, Happy Meal toys—go into a landfill. In Willimantic Waste Paper’s single-stream system, that’s about 5 percent of the material it collects.
