A man walks into a bar and orders a glass of 21-year-old whiskey.

He takes a sip, then immediately spits it out.

“I asked for a 21-year-old whiskey! This is only 18 years. I’m not paying for this! Bring me a 12-year-old cognac instead.”

The bartender complies, but again, the man spits it out.

“This is only 10 years old! I’m not paying for that either!”

Frustrated after several rounds of the same routine, the bartender pours another drink and says,

"This one’s on the house."

The man takes a sip, spits it out once more.

"This tastes like piss!"

The bartender sighs and replies,

"Alright, genius, now guess how old I am?"

Nicholas Joseph Callan

Died 10 Jan 1864 at age 64 (born 22 Dec 1799).Irish physicist who pioneered in electrical science. Heinvented the induction coil (1836) before that of better-known Heinrich Ruhmkorff. Callan's coil was built using a horseshoe shaped iron bar wound with a secondary coil of thin insulated wire under a separate winding of thick insulated wire as the “primary”coil. Each time a battery's current through the “primary”coil was interrupted, a high voltage current was produced in the electrically separate “secondary”coil. By 1837, Callan used a clock mechanism to rock a wire in and out of a small cup of mercury to interrupt the circuit 20 times/sec on a giant induction machine, producing 15-inch sparks (estimated at 600,000 volts).«
