Sodding hedonists...

I actually remember the stuff they teach you in high school, in addition to the copious amounts of books I already read. Yeah, I will teach Greek Fire, black powder, and nitroglycerine to the Romans. All three are quite easy for me to make (I know, the recipe we know for Greek Fire is not the original, but hell, it is close enough).

In any case, I want power. Oh yeah. Lots of it. Not just some smelly barbarian chieftain or saddle-sore nomad khan. No, while I am in Antiquity, I may as well wish for the moon. I will become the Emperor of the Roman Empire with my knowledge and then on a single night, execute all the Praetorians. Just like Hitler and the Sturmabteilung (SA), a.k.a. Brown Shirts.

After that I will introduce the Bessemer process to mass-produce stainless steel (with nickel), and then invade what is now modern-day Ukraine to mine titanium, and see if it will be possible to work with it, using the newly-designed furnaces. I will teach the Romans how to build trebuchets if the cannons prove to be weak, although I could rifle them too (but that would mean it would take very long to reload them, as I do not know how to make an effective breech-loading cannon). Then I will introduce oil and coal as energy sources. The list goes on... With coal I can make sulphuric acid, which I do not doubt will become a superb wall-defence weapon. Ahh, chemistry was always my favourite science after astronomy.

Continuing, I would introduce vaccination and antibiotics (I know of a couple of natural sources of antibiotics which perhaps I could isolate) to make my empire impervious even to the plague which will hit it (supposing I come before Marcus Aurelius). Not to mention my meagre medical knowledge would nevertheless revolutionise medicine, and of course, I would ban the use of lead and mercury in sensitive places.

Heh, I could write a book about this...
