Women in STEM
Just some of the the women working in STEM fields who have helped me make videos over the years!!!
Posted to coincide with International Day of Women and Girls in Science.
The beginning of photography
Some amazing stuff at the Royal Society for the latest Objectivity video.
It all started with this old paper/letter from a guy called William Henry Fox Talbot in 1839.
Love the title...
Some Account of the Art of Photogenic Drawing or, the process by which natural objects may be made to delineate themselves, without the aid of the artist's pencil.
So basically, photos!
He goes on to explain...
I proposed to spread on a sheet of paper a sufficient quantity of the nitrate of silver; & then to set the paper in the sunshine, having first placed before it some object casting a well defined shadow.
And so the letter continues - an amazing glimpse into the earliest days of photography.
It is little surprise this amazing document has been valued at £800,000, or about $1.2 million.
Keith Moore (head librarian at the Royal Society) also showed us an extraordinary collection of very early photos (some are posted below).
See more about them in our video.
TEASER: One is worth more than the others. In fact it has been valued at £500,000 ($720,000).
Photos from ESO
I was just going through some old material from my trip to the European Southern Observatory in August, 2013.
Even now, I'm still posting new videos from the trip to Deep Sky Videos.
But looking at my archive of still photos, there are lots of great pictures I've hardly looked at.
Here are a handful:
Letter in French
Here's the letter from the latest "White Gloves of Destiny" episode of Objectivity, as "found" by special guest Charlie McDonnell.
Feel free to leave a translation in the comments under the original video.
What makes Stripey Clouds?
In the latest Sixty Symbols video, Professor Mike Merrifield explains what makes stripey clouds like these.
I think the clouds are called radiatus.
Artwork and animation in the video were by Pete McPartlan.
