I don't know how many people are aware of this, but famous scientist Isaac Newton was, according to the calender in use in England at the time (the Julian calendar), born on this date in 1642.

So, perhaps we could celebrate his 374th birthday today. (Or, one could argue that he doesn't turn 374 until January 4, which is his birthday in the modern Gregorian calendar, and that his birthday should be celebrated then.)

Wasn't Newton proven wrong?

Yes, but...

1. That didn't happen until well after his lifetime.
2. The replacement theory builds off Newton's theory. That's the way science (and mathematics) works; one theory builds off another.
3. Newtonian mechanics are still accurate enough if you are not talking relativistic speeds or quantum scales, and are much easier to work with.

Also, Newton was one of the two people who (independently) invented calculus.

So it's kind of Virgin Day (as he was virgin too)?

Isaac Newton is the person who invented e.g. the gravity. Before that people used to just kinda float around.

He also invented differential calculus. Before that all we had was indifferential calculus, which nobody really cared about.

For me, everyday is Virgin Day.

Same here buddy. Same here.

What's your birthday, I want to celebrate Deatrice Day?

Huh, wasn't aware of this, thanks for informing us dtgreene. I actually tried googling that, and then got the joke not too soon after.
