An epic lunar laser experiment is still going strong, five decades after the Apollo astronauts set it up on the surface.
The moonwalking crew of Apollo 11, which landed on the moon 50 years ago this month, put special retroreflectors on the lunar surface, as did the later crews of Apollo 14 and 15, in 1971. (Another retroreflector, built by the French, sits on the Soviet Lunokhod 2 rover that landed without a crew in 1973.)
I call them “BATS”.
Can bacteria generate radio waves?
On the face of it, this seems an unlikely proposition. Natural sources of radio waves include lightning, stars and pulsars while artificial sources include radar, mobile phones and computers. This is a diverse list. So it’s hard to see what these things might have in common with bacteria that could be responsible for making radio waves.
But today, Allan Widom at Northeastern University in Boston and a few pals, say they’ve worked out how it could be done.
Image capture is the portion pertaining to what they cannot do to civilians. As it stands anyway. Just to name a few: weather mod, Chemtrails, extraterrestrial weapons, low frequency and ULF… Ultra low frequency, mood management, and lazers.
A number of events are planned next week on the Mall to commemorate the 50th anniversary of the historic moon mission.

ATOMS
The smallest unit of matter that can be imaged my microscopy today is the atom. The use of high resolution electron microscopy or HREM enables the scientist to study the neat lines and rows of atoms arranged in their unit cells. The world of atomic level microscopy is bathed in hyperbole. Imaging an atom at a magnification of x 100 million is equivalent to observing from Earth the golf ball that Neil Armstrong hit on the moon. The microscopists at the forefront of high resolution imaging are now trying to read the golf ball’s number!

Atomic interactions in everyday solids and liquids are so complex that some of these materials’ properties continue to elude physicists’ understanding. Solving the problems mathematically is beyond the capabilities of modern computers, so scientists at Princeton University have turned to an unusual branch of geometry instead.
Researchers led by Andrew Houck, a professor of electrical engineering, have built an electronic array on a microchip that simulates particle interactions in a hyperbolic plane, a geometric surface in which space curves away from itself at every point. A hyperbolic plane is difficult to envision—the artist M.C. Escher used hyperbolic geometry in many of his mind-bending pieces—but is perfect for answering questions about particle interactions and other challenging mathematical questions.
The research team used superconducting circuits to create a lattice that functions as a hyperbolic space. When the researchers introduce photons into the lattice, they can answer a wide range of difficult questions by observing the photons’ interactions in simulated hyperbolic space.
