Monarch Butterfly Metamorphosis (Colored Pencil Sketch)
FYI: The Monarch Butterfly’s migration and everyday navigation are achieved via the sun’s position, determined by a time-compensated solar compass coupled with a circadian clock within their antennae, and assisted by the earth’s magnetic field for orientation, due in part to crypto chrome, a photoreceptor protein sensitive to the violet-blue part of the spectrum. In presence of violet or blue light, it can function as a chemical gyro-compass, which confirms it’s alignment with the magnetic field; although, it cannot determine the difference between magnetic north/south. Each individual antennae possess this complex chemical advantage.

Great Lives | Carl Sagan
Physicist Brian Cox tells Matthew Parris how Carl Sagan’s ‘Cosmos: A Personal Journey’ television show changed his life.
As a young boy of 13, Brian Cox stared at his television screen every Wednesday evening, as Carl Sagan took him on a journey across the Cosmos. The programme was a ground-breaking piece of television by a brilliant young scientist who could be inspiring and infuriating in equal measure.
Sagan was a complex character. Driven to succeed, he came from a relatively poor background to become a millionaire, and one of the most influential scientists of his era. His popularity left him open to both criticism and jealousy amongst his colleagues, and whilst he was passionate about the need to educate the populace, he could also be arrogant and dismissive of his fellow scientists.
So just how good a scientist was he, and what is his legacy? Listen to this 30-minute broadcast/interview for more on the powerful influence of science and the importance of science communicators such as the late Carl Edward Sagan.
Anonymous asked: Thanks for answering the Einstein question (I asked some other users too, in case you didn't answer, but you were the first to answer, actually). My friend asked me it, and I wasn't too sure I had the correct answer.
Absolutely. May I recommend this book :)
Also, “why does e=mc^2?” by Brian Cox and Jeff Forshaw.
Another reason why I love Brian Cox.
I’ve gotten this response before. And it truly has gone down like this:
Them: Do you really think we’ve landed on the moon? or Yeah but I dunno, who knows what they’re doing, the moon landing was obviously faked, have you seen __________ (some documentary)?
