If the earth is old, then radioactive isotopes with short half-lives should have all decayed already. That is what we find. Isotopes with half-lives longer than eighty million years are found on earth; isotopes with shorter half-lives are not, the only exceptions being those that are generated by current natural processes (Dalrymple 1991, 376-378).

Primordial weirdness: Did the early universe have one dimension? Scientists outline test for theory
ScienceDaily (Apr. 20, 2011) — Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010. They suggested that the early universe -- which exploded from a single point and was very, very small at first -- was one-dimensional (like a straight line) before expanding to include two dimensions (like a plane) and then three (like the world in which we live today).

Graphene Will Change the Way We Live | Dr. Kaku's Universe | Big Think
The theory behind the substance graphene was first explored by theoretical physicist Philip Wallace in 1947 as kind of a starting point when he was doing research trying to understand the electronic properties of more complex, 3D graphite. although the name graphene wasn't actually coined until 40 years later, where it was used to describe single sheets of graphite.Multimedia

Though there are no official stats to prove this, but according to the general observation of the washroom usage habits of the general population, one can deduct that women’s restrooms tend be occupied more often than men’s restrooms are. Since men’s restrooms are fitted with urinals, they don’t need to occupy stalls while women on the other hand don’t have any such handy choices.World of Ends - what the internet is
