The Bigger Picture

I'm sure you've heard the phrase "to look at the bigger picture". In other words not to look at a specific issue but rather to view it in a larger context. Well if you've got issues with money, work or just life in general I have the very picture for you. One that may make you realise that your problems really do pale in to insignificance in the grand scheme of things.

On January 5th 2015, NASA released an image of the Andromeda galaxy, which is the closest galaxy to us. They captured the image using the NASA/ESA Hubble Telescope. It consists of 411 images and put together it is the largest image ever taken. It is 69,536 x 22,230 pixels, that’s a whopping 1.5 billion pixels and requires about 4.3 GB of disk space!

Backlight

Many amateur photographers hold on to the belief that when photographing portraits in natural light, you must have the sun behind you. Whilst this is not a bad thing to do, you, with a little effort and planning you can get some wonderful effects by the opposite of shooting in to the sun. Karl Taylor explains and demonstrates.

SDO Year 5

February 11, 2015 marked five years in space for NASA's Solar Dynamics Observatory, which provides incredibly detailed images of the whole sun 24 hours a day. Capturing an image more than once per second, SDO has provided an unprecedented picture of how massive explosions on the sun grow and erupt. The imagery is captivating, allowing one to watch the constant ballet of solar material through the sun's atmosphere, the corona. In honour of SDO's anniversary, NASA has released a video showcasing highlights from the last five years.

Batman

A nice montage through the evolution of Batman on the big screen. From the serials of the 1940s to the Christopher Nolan blockbusters, we can see how the portrayal of the character has changed to suit the times. As one commenter put it, "The Good, The Bad and the Campy".

Left, Right?

Today, about one-tenth of the world’s population are left-handed. Why such a small proportion, and why does the trait exist in the first place? Daniel M. Abrams investigates how the uneven ratio of lefties and righties gives insight into a balance between competitive and cooperative pressures on human evolution.

Bottle Rocket

The Royal Institution explain the science behind a rather beautiful demonstration they do with a water cooler bottle and a small amount of ethanol. I used to love watching the Christmas Lectures when I was younger and its videos like this that remind me why.

FPS

The chaps at the Slow Mo Guys YouTube channel have given us lots of great videos as they film things at very high speeds in order that we can see what would normally be missed by the human eye. I have featured a few here at e-clecticism. This one is particularly interesting to me. What the shutter inside a digital SLR looks like when filmed at 10,000 frames per second. Thanks to my friend Will for spotting this one.
