- One rationally comprehensible universe.
Not just any universe. You’ll need to be particular here. It must be a rationally comprehensible, rationally ordered cosmos. Not a chaos, a cosmos, I must insist on this point.
Next, you’ll need
- One consistent set of discoverable laws.
Some of the boys and girls will claim that you don’t need the laws yet – science will produce them for you later. But that’s just silly, isn’t it children? You might not know the laws yet but you need there to be laws. And you need to trust that they’re out there and that you have ways of approaching them.
Thirdly, you'll need
- At least one rational scientist.
This one ought to go without saying, but you’d be surprised how often it gets left out of the ingredients list!
And finally – this is the one you were all waiting for...
- A scientific method by which to proceed.
Now if you’ve been following us for a while, the good news is you’ll have a scientific method left over from yesterday’s activities. If you haven’t already got a scientific method, please don’t just “borrow” one from the other children. That really isn't fair. You should go back to the original episodes and build it up from first principles. A scientific method is made from very expensive ingredients, and if you haven’t bought them yourself, then using someone else’s method is stealing.
So there you have it – the four ingredients you need to do science. Now before you all complain... before you all complain – yes I know... I know that none of you can afford the ingredients. I’m sorry about that, but that’s the way it is. When we’re dealing with such valuable things, there’s no way around it.
All I can say to you is this: If you want to do science – and I sincerely hope that you do – you can’t take shortcuts, you must have these ingredients. If you don’t have them – and you don’t – then you’ll have to ask Mum or Dad.
