BBC Crew Rescue Trapped Penguins in Unprecedented Move

 

While filming “Dynasties” with Sir David Attenborough in Antarctica, the BBC wildlife film crew made an unprecedented decision to help rescue some penguins.

One of the ‘cardinal rules’ of wildlife documentaries is to not intervene or interfere with events they are attempting to capture on film. After grappling with the decision, the crew determined that the intervention didn’t pose any danger to them or the animals; that they weren’t changing the dynamics of the natural system; and that they weren’t depriving any other creatures of food.

According to The Guardian, many top leading wildlife camera operators and film-makers have defended the film crew’s decision. Additionally:

 

Mike Gunton, the executive producer of the series, also defended the crew’s decision to help the penguins. He told Radio 4’s Today programme: “In the 30 years I’ve been doing this, it’s one of the very few occasions when we’ve ever done anything like this because it’s a very unusual situation. Normally, you don’t interfere, you can’t interfere, or you wouldn’t interfere because of all sorts of consequences.
 
“One, it would be very dangerous to do often for both you and the animal. Also, you’ll probably be changing the dynamics of the natural system or you might be depriving something of its food. But, in this particular situation, none of those things applied.”
 
While it has previously been reported that Attenborough had opposed the move, saying that “tragedy is a part of life”, Gunton said that the presenter had told him he also would have rescued the penguins. [source]

This Viral “Schrödinger’s Cat” Photo Took Me Way Too Long to Figure Out

schrodingers cat pic reddit trippy illusion This Viral Schrödingers Cat Photo Took Me Way Too Long to Figure Out

 

So this was the top trending photo on reddit yesterday and I’m okay admitting that it took me a while to figure it out. At first I just assumed ‘photoshop’ but finally realized the box is on one side and the cat is simply on the other, duh! The simple reflection creates the illusion.

Anyway, on to the obligatory Wikipedia entry on Schrödinger’s cat:

 

Schrödinger’s cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935, during the course of discussions with Albert Einstein. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The scenario presents a hypothetical cat that may be simultaneously both alive and dead, a state known as a quantum superposition, as a result of being linked to a random subatomic event that may or may not occur.
 
A cat, a flask of poison, and a radioactive source are placed in a sealed box. If an internal monitor (e.g. Geiger counter) detects radioactivity (i.e. a single atom decaying), the flask is shattered, releasing the poison, which kills the cat. The Copenhagen interpretation of quantum mechanics implies that after a while, the cat is simultaneously alive and dead. Yet, when one looks in the box, one sees the cat either alive or dead, not both alive and dead. This poses the question of when exactly quantum superposition ends and reality collapses into one possibility or the other.

Shark Attack Test – Human Blood vs Fish Blood

 

If blood makes you squeamish I would skip this one

 
Mark Rober revisits his shark attack blood test to see if sharks prefer fish blood to mammal blood.

Rober’s experiments are usually a bit more rigorous (even the original seemed more scientific). In this test, the fish blood also consisted of flesh and other parts of the fish so not exactly a direct comparison.
