Major Scientific Discoveries - Timeline

[rally]

OK - pivotal inventions usually involve the application of a new discovery

- discovery of the properties of doped silicon semiconductors leading to the modern family of semiconductors such as the transistor and the electronics/computer revolution - Russell Ohl 1940, leading to Alan Shockley's 1948 discovery of the junction transistor. and others who took this further.

- then Babbage certainly theorised and discovered that it was possible to build a machine that can compute - even if he didnt completely build it - he spent his life (and fortune) campaigning for it, even if the politicians and scientists of the day didnt believe him.

Well, in that vein you can frame everything as a discovery. Henry Ford discovered that it was possible to build cars on an assembly line.

Do you think that Neutrinos having mass be a good discovery (1998) or not, but recent theoretical considerations is that Neutrinos maybe the make up of Dark Matter or at least a lot of it.

interesting notion....do you have a reference for that claim??

[mswhin63 (Malcolm)]

Hi one reference, not fully studied though. I lost the other one, still searching

The dark matter possibility may have stem from the latest mass estimate of 1/1000th compared to old estimates of 1/1000000 although I lost that reference sorry. Anyway the theory is speculative not confirmed.

Here is the speculative thoughts

Great, thanks Malcolm
