After their victory over the White Sox last night the possible scenarios (all in all 21 games involving the Twins or Tigers = 2,097,152 scenarios) for the Twins look like so:
0.9% of the scenarios have the Twins clinching the division on the road in the Detroit series.
9.6% of the scenarios result in a game 163 (tie atop the division)
15.0% of the scenarios have the Twins winning the division in 162 games.
So 1 in 4 possible scenarios result in the Twins playing more than 162 games this season. After this summer, I guess I’ll take it.
At St. Buchardi church in Halberstadt, Germany, the performance of John Cage’s “As Slow As Possible” continues with a note change today. This chord will last for 16 months (until next July).
Organizers in Halberstadt rejected questions about what it all means.
“It doesn’t mean anything,” one of them said. “It’s just there.”
Scheduled completion of the performance – the year 2639.
The Production of Molecular Positronium –

From the abstract:
It has been known for many years that an electron and its antiparticle, the positron, may together form a metastable hydrogenlike atom, known as positronium or Ps. In 1946, Wheeler speculated that two Ps atoms may combine to form the dipositronium molecule (Ps2). … Because Ps has a short lifetime and it is difficult to obtain low energy positrons in large numbers, Ps2 has not previously been observed unambiguously. Here we show that when intense positron bursts are implanted into a thin film of porous silica, Ps2 is created on the internal pore surfaces. This result experimentally confirms the existence of the Ps2 molecule and paves the way for further multipositronium work.
I just thought it was amazing that positronium has existed and had an elemental symbol (Ps) for the last 60 years and yet, as a fairly advanced student of chemistry, I had never heard of it. These Ps2 molecules only exist for 0.4 nanoseconds before the electrons and positrons annihilate each other, so it’s not the most stable of systems, but it’s still pretty cool that its possible to create an atom that has a weight less than 1/1000th of a hydrogen atom.
