Astrology, Spirituality & Alternative Healing

reminds me of a couple of science-fiction shorts stories I read ages ago. In the first one, the main character wonders why he keeps getting mismatched socks in his dryer while sometimes losing one of his own at the same time. He happens to be a physicist (or some such scientist/engineer) and hooks all his lab equipment to his dryer for a series of tests. He ends up discovering the technology of teleportation in the end

The other story had to do with how quickly the Postal Service always managed to deliver the letters (and packages) of the main character that were further away than across the street. After a series of test-mailings to farther and farther places across the planet, he finally addressed a letter to the "Galactic Federation, Alpha Centauri" (or a similar outrageous address.) The first letter was returned as "No Such Address" so he sent a second one to the same address, just to be sure. He is then congratulated by the representatives from the Galactic Federation for discovering the secret of their postal delivery system, and Earth is accepted into their midst.

I can't remember who wrote either of these, just that both have to do with things "traveling" faster than we understand now, or going through dimensions to get somewhere else. I don't really have any real life examples of my own, as I'm not a good housekeeper either. If things go missing, it's likely because they're under a pile of to-be-shredded junkmail
