Yes a little! history of diabetes is very old. It is documented even in the ancient Egyptian and some of the old Indian texts, these must be about 2000 years or so. Even at that time, they found that urine of diabetic patients was sweet and actually attracted ants. Of course the disease was not so well known, but still they could make out that something is not normal!

if you go right back to the beginning computer graphics probably starts in the late 1800’s… People like Babbage were experimenting with the idea of computing machines, and around the same others were experimenting with phospherscense and discovered they could make a glass tube with a vacuum and and electrical field in it that would cause a phosphor screen do glow due to unknown “rays” which came from the electrical “cathode”. They called it the Cathode Ray Tube or CRT, and it went on to become the TV screen, and subsequently computer monitor.
Von Neumann and Turing (Turing gets a lot of credit in the UK, which is well deserved, but Von Neumann did a lot similar things, and made more discoveries in more fields than some entire universities do. His list of discoveries is unbelievable) started figuring out how computers could actually be made, and what they could do around the 1940’s.
Almost as soon as it became possible to build computers, people figured they could hook them up to CRTs…. and play games on them! Sutherland was one of the guys who started figuring out how to get computers to draw on the screen. Bresenham is famous for figuring out how to draw lines!
Skip forwards a few years to the 70s and we start to think about doing decent 3D graphics. Ed Catmull, invented a whole load of techniques as a researcher in the 70’s (then went on to set up Pixar, and now runs Disney animation – but don’t think he’s an admin guy… He got there as a scientist!), Jim Blinn developed a lot of stuff about how surfaces might look. Whitted invented ray tracing, Cook and Loren Carpenter (now working for Catmull) developed all that into something that could be used on movies. Ken Perlin figured out how randomness could be used to make images look more real. Meanwhile Tom Duff and Tim Porter figured out how images were layered together which opened the way for video editing, and compositing.
It’s actually pretty easy to know this stuff as its a relatively new field (though it builds on what came before), so all of the last set of guys are all still around. I’ve met a lot of them, and at least been in the same room as almost all of them.

Microbiology is a recent field of science, as it is the study of microorganisms whose existence has not always been known. It wasn’t until the invention of the microscope by Antonie van leeuwenhooek in the 1600s that bacteria were first observed. But it took nearly 200 years for us to learn more about them.
It wasn’t until the 1800s that Louis Pasteur actually proved that microorganisms are everywhere and cause things to turn bad, such as milk, in his famous swan neck flask experiment. Before this experiment, people thought living things came from things with no life spontaneously – such as maggots in meat – called spontaneous generation. Louis Pasteur proved this theory wrong by showing microorganisms are in the air all the time and do not appear spontaneously.
This led to the pasteurisation of milk and the field of microbiology, where scientists began growing and investigating microorganisms. Robert Koch is an example of a great microbiologist, who at around the same time as Louis Pasteur, begun linking bacteria to diseases, discovering the causes of diseases such as cholera and tuberculosis which led to the treatment of many illnesses.
