That depends. You can send lavish gifts. You can send tender love letters. But if your love just takes the form of you yourself with a brimming heart… then, yes, you can send it through the mail, but we don’t recommend it. One star-crossed lover in China has already attempted it. He talked a co-worker into taping him into a cardboard box addressed to his girlfriend across town. Unfortunately, the courier got lost, and what should have been a 30-minute trip stretched on for 3 hours. The man later explained that he realized that he was running out of air, but the cardboard was too thick for him to make a hole. He could have shouted for help but, you know, he didn’t want to spoil the surprise. And what a surprise it was. When the unsuspecting woman opened her unexpected package, what she found inside was indeed her boyfriend—unconscious and nearly suffocated to death. Paramedics were quickly called, and the parcel’s hapless contents were successfully revived.
If so, then you are probably a tennis player. And in that case, you also know that tennis has a scoring system that is unique among sports. Perhaps most familiar is the fact that zero points is known as Love. There are various theories about the origin of that strange application of the word, but they all can be traced back to France where the game itself originated. It is possible, for example, that 16th century players colloquially referred to 0 as “the egg” because of its shape. That’s “l’oeuf” in French, which would later be Anglicized to be pronounced “love.” Other people think it’s more likely that the term derives from a period idiom about playing “for the love of the game,” which meant that someone was playing without money wagered on the outcome. Whatever the case, the terminology has made tennis the perfect game for Valentine’s Day, because even if you can’t score you’ve still got Love.
In the 7th century A.D., Æthelthryth—better known by her Anglicized name, Audrey—was a daughter of East Anglian (present-day England) royalty who, despite becoming a queen, was primarily interested in a life of spiritual devotion. She even became a nun and founded her own abbey before eventually passing away and being canonized as a saint. Legend has it, however, that one folly that lingered from St. Audrey’s highborn youth was a love of necklaces. And so the locals began to commemorate her by producing fine, lace necklaces. Fast forward to the 17th century, when three significant changes had occurred: The lace necklaces had grown to become low-quality goods sold to those on pilgrimage. The Puritans had ascended to power, and were busy looking down their noses at anything that smacked of prideful frippery. And the name of St. Audrey’s Lace had gradually been shortened to Tawdry Lace. Thus, the word “tawdry” came to mean anything cheap and vulgar.
You’d never guess and answer. First, because the answer is the tuatara, an animal you probably haven’t heard of unless you’re from New Zealand. And second, because its record-setting evolutionary rate is disguised by the fact that its appearance hasn’t changed much in millions of years. The tuatara resembles a lizard, except that it has features that are more closely related to fish and birds, as well as some truly unique attributes, such as a light-sensing third eye. These creatures are the last living members of an order of animals that thrived during the Mesozoic period (as in, the age of dinosaurs), and they actually predate the appearance of lizards and snakes. But while fossils reveal that the tuatara looks essentially the same now as it did then, DNA extracted from those fossils compared to DNA from living specimens reveals a faster rate of change than is found in any other animal. Sadly, climate change is having an adverse effect on the tuatara: their gender is determined by the incubating temperature of each egg, and as their habitat grows warmer, fewer and fewer females are being born. While they may be the fastest evolving species on earth, evolution itself is such a slow process that it won’t be able to outpace this problem.
Yes. It’s not only possible, but we have actual time travelers walking among us today. According to the Theory of Relativity, it is possible for speed or gravity to make time pass differently for separate observers. If that sounds vague and science-y, maybe a real-world example will help: if highly accurate, atomic clocks are aligned perfectly on earth, and one of those is sent into space, then one of those clocks will run faster than the other one. This is not caused by a mechanical problem with the clock, but happens through time itself being bent by the forces involved in space travel. So, all of those astronauts hanging out on the space station? Their time is passing faster than ours, and when they return to earth, they are actually younger than they would be if they had remained here. Ok, so not much younger, but it’s still true. Michael Finke and Peggy Whitson, who have spent more time on the space station than any other American man and woman, are 0.0093 and 0.0092 seconds younger, to be exact. And the man who has spent more time on the space station than anyone in history—Russia’s Sergei Krikalev, with 803 days in orbit—is a full 0.02 seconds younger! Maybe one day we will be able to reverse the time dilation, and these explorers can tell us about the wonders of life half a second in the future!
