Who took the photo of the first man on the Moon?

C. Stuart Hardwick:

If you mean this:

This is a frame from the slow-scan, low resolution TV camera mounted in the Modularized Equipment Stowage Assembly (MESA). The MESA folded down out of a small equipment bay clockwise from the ladder (as you look down on the LEM) when Neil Armstrong pulled a release prior to descending to the surface.

The image above shows the MESA deployed, so that the camera is roughly upside down, its pistol grip protruding at the top center of the frame, its lens facing away. Here is a closeup of the camera from the other side:

By today’s standards, this was a pretty crappy camera, but it was a technological wonder at the time, some dozen times smaller than the commercial TV cameras of the time. Because it transmitted in a non-standard format, and because footage of the moon landing had to be broadcast over dozens of different formats around the world, all the images you’ve ever seen from this camera were actually filmed second hand, off high-intensity TV monitors provided by NASA for that purpose. The whole rig was hopelessly crude and expensive, but that was the only way to do it at the time.

If you mean this (and any of several similar images):

This is Buzz Aldrin (the second man to leave the LEM), photographed by Neil Armstrong (the first) using a 70mm Hasselblad medium format film camera, to this day one of the finest cameras ever made, loaded with a specially made magazine of fine-grained Kodachrome film on an ultra-thin mylar base that permitted each magazine to hold twice as many feet of film as on standard commercial stock.

These cameras were modified such that they could be mounted on the astronaut’s chest:

What Is the Difference Between Generic and Name Brand Ibuprofen?

What is the difference between generic ibuprofen vs. name brands?

Yali Friedman:

I just published a paper that answers this question: Are Generic Drugs Less Safe than their Branded Equivalents?

Here’s the tl;dr version:

Generic drugs are versions of drugs made by companies other than the company which originally developed the drug.

To gain FDA approval, a generic drug must:

  • Contain the same active ingredients as the innovator drug (inactive ingredients may vary)
  • Be identical in strength, dosage form, and route of administration
  • Have the same use indications
  • Be bioequivalent
  • Meet the same batch requirements for identity, strength, purity, and quality
  • Be manufactured under the same strict standards of FDA's good manufacturing practice regulations required for innovator products

I hope you found this answer useful. Feel free to reach out at www.thinkbiotech.com. For more on generic drugs, you can see our resources and whitepapers at Pharmaceutical strategic guidance and whitepapers

Big Questions
Do Cats Fart?

Certain philosophical questions can invade even the most disciplined of minds. Do aliens exist? Can a soul ever be measured? Do cats fart?

While the latter may not have weighed heavily on some of history’s great brains, it’s certainly no less deserving of an answer. And in contrast to existential queries, there’s a pretty definitive response: Yes, they do. We just don’t really hear it.

According to veterinarians who have realized their job sometimes involves answering inane questions about animals passing gas, cats have all the biological hardware necessary for a fart: a gastrointestinal system and an anus. When excess air builds up as a result of gulping breaths or gut bacteria, a pungent cloud will be released from their rear ends. Smell a kitten’s butt sometime and you’ll walk away convinced that cats fart.

The discretion, or lack of audible farts, is probably due to the fact that cats don’t gulp their food like dogs do, leading to less air accumulating in their digestive tract.

So, yes, cats do fart. But they do it with the same grace and stealth they use to approach everything else. Think about that the next time you blame the dog.
