[edit] Mistake in dating?

I can't help but notice that after speaking of his death in 1802, the article discusses a person he referenced in a work he completed in 1803, was this information checked? Shinzen 04:32, 3 March 2007 (UTC)

I have the Darwin family tree done in PowerPoint. Please post on my talk page to request changes or email me to get a copy of the PowerPoint.Cutler 21:22, 3 Mar 2004 (UTC)

[edit] Added Big Bang and Big Crunch Details

Text added that proves Erasmus Darwin theorized and documented the Big Bang and Big Crunch theories over a century before anyone else. --GBoehm 20:08, 28 Feb 2005 (UTC)

[edit] Rocket engine?

The foll was posted by an anon: I have removed it until anyone can verify it. The idea seems unlikely, but not impossible, given Priestley's recent work with gases. But I would certainly question whether such an arrangement would be for propulsion, or simply for experiment/water creation. JackyR 19:43, 12 March 2006 (UTC)

===Rocket engine===

In notes dating 1779, a sketch of a simple liquid-fuel rocket engine can be found, with hydrogen and oxygen tanks connected by plumbing and pumps to an elongated combustion chamber and expansion nozzle, a concept not to be seen again until one century later.

Here you can read: "He suggested the oxygen-hydrogen rocket engine," . If you google "Erasmus Darwin" and "rocket engine" or "Erasmus Darwin" and "ramjet" or "rocketry", you find various references. I reestablish the paragraph if you don't mind. Hektor 22:34, 18 June 2006 (UTC)

[edit] Practice/practise

Chambers dictionary (Edinburgh) gives:

• "practice n"
• "practise, (N Am) practice vt".

So this article, being about a Brit, should use practise for the verb. JackyR 19:55, 12 March 2006 (UTC)
