Mother Teresa's Heavenly Experience

When Mother Teresa died and went to heaven, God greeted her at the Pearly Gates.
"Be thou hungry, Mother Teresa?" asked God.
"I could eat," Mother Teresa replied.
So God opened a can of tuna and reached for a chunk of rye bread and they began to share it. While eating this humble meal, Mother Teresa looked down into Hell and saw the inhabitants devouring huge steaks, lobsters, pheasants, and pastries. Curious, but deeply trusting, she remained quiet.
The next day God again invited her to join him for a meal.
Again, it was tuna and rye bread. Once again, Mother Teresa could see the denizens of Hell enjoying lamb, turkey, venison, and delicious desserts. Still she said nothing.
The following day, mealtime arrived and another can of tuna was opened. She couldn't contain herself any longer.
Meekly, she asked, "God, I am grateful to be in heaven with you as a reward for the pious, obedient life I led. But here in heaven all I get to eat is tuna and a piece of rye bread and in the Other Place they eat like emperors and kings! I just don't understand it..."
God sighed. "Let's be honest Terry," he said, "For just two people, it doesn't pay to cook."

Metre

In 1889, the third legal definition of the metre was adopted at the Paris General Conference. An international prototype metre bar was made of a 90-10 platinum-iridium alloy with an X cross section to minimize flexing. The metre was defined as the distance measured between two lines on the bar at the temperature of freezing water, 0°C. The alloy ingot was made possible by a high-temperature furnace devised by Henry Sainte-Claire and his assistant Jules Henry Debray. The alloy was harder than pure platinum, but retained the other desireable properties, including resistance to corrosion. Duplicate prototypes were made and distributed to each of the countries that joined in the international agreement. The same alloy was used to prepare the international protype of the kilogram.«
