Ah. I wasn't aware of the discovery of Bs. I was taught the elements from 1 through 217, but that was years and years back and in my high school chemistry class. Granted, we had to create elements 104 to 217, but that wasn't a problem because back then we were well educated young people, not like nowadays when the students couldn't build a linear accelerator or a cyclotron or bevatron out of tinfoil and burnt matchsticks if their lives depended upon it. Why, did you know that Quantum Mechanics and Tensor Calculus aren't even taught in the grade schools anymore??? I was shocked, I tell you, shocked to my very core! Back in my day we only had a slide rule and/or an abacus to work out problems, but today, even with all the fancy calculators and computers you can't find a sixth grader who can integrate a nested trig function correctly! And as for matrices, well, just forget it!
