You know it has a two year half life.

Eleven radioisotopes have been characterized, with the most stable being 44Ti with a half life of 63 years, 45Ti with a half life of 184.8 minutes, 51Ti with a half life of 5.76 minutes, and 52Ti with a half life of 1.7 minutes.

All of the remaining radioactive isotopes have half lives that are less than 33 seconds and the majority of these have half lives that are less than half a second.

This is after one half life.

A two year half life.

It has a half life of 35 days.

less than halfway through the Earth's life?

It has a half life of about three hours in humans.

After one one half life, what happens?

So now you have, after one half life So

The most stable of these is 120m1Sb with a half life of 5.76 days.

The half life for the decay of is only 6.7(17) seconds.

Let's think about what happens after another half life.

let's just call it x, and it has a half life of two years.

Francium 223 is the most stable isotope, with a half life of 21.8 minutes, and it is highly unlikely that an isotope of francium with a longer half life will ever be discovered or synthesized.

Pyridostigmine is a short lived drug, with a half life of about four hours.

It also has 35 radioisotopes, of which the longest lived is 125Sb with a half life of 2.75 years.

The most stable radioisotope is tritium, with a half life of 12.32 years.

It decays through neutron emission with a half life of (1.39 0.10) 10 22 seconds.

Omar? My...the great...my Omar?

So if you go back after a half life, half of the atoms will now be nitrogen.

Now there is no Omar.. they killed Omar

So if we go to another half life, if we go another half life from there, I had five grams of carbon 14.

From the age of Omar Al Faruq to the revolutions of Omar Al Mukhtar.

Eighteen radioisotopes have been characterized, with the most stable being 53Mn with a half life of 3.7 million years, 54Mn with a half life of 312.3 days, and 52Mn with a half life of 5.591 days.

But could they have predicted this unprecedented spike less than halfway through the Earth's life?

Upon his return, however, Omer was detained by Shin Beit, only to reappear half a day later in an ambulance.

It decays through double neutron emission and has a half life of at least 9.1 10 22 seconds.

And we could keep going further into the future, and after every half life, 5,740 years, we will have half of the carbon that we started.

Yes, Omar yes! No, not Omar.

All of the remaining isotopes have half lives shorter than 1.6 days, and the majority of these have half lives less than 1.8 seconds.

It's lasted longer than your promises.

During the half century of the Fifth Republic, a bipartisan system of left and right has traditionally prevailed.

The biological half life (the average time it takes for the human body to eliminate half the amount in the body) for uranium is about 15 days.

Umar!

Seal.

Reload!

Astronomical measurements show that the proton to electron mass ratio has held the same value for at least half the age of the universe, as is predicted by the Standard Model.

Omar Suleiman, and the guy behind Omar Suleiman.

Now after another half life you can ignore all my little, actually let me erase some of this up here.

Expiry Age

Seal torpedo.

Prime the gun.

He'll never die, that old man, he'll live longer than the mountains.

How old is your father?
