Juneteenth is a special day in history. President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, but it did not reach the slaves in states that were part of the Confederacy until much later. The Emancipation Proclamation finally reached Texas on June 19, 1865. Because of this, we celebrate Juneteenth. Juneteenth is mostly celebrated in Texas and surrounding states.
There is a history of smallpox inoculation that goes back as far as 1000 AD in China, Africa, and Turkey. However, the person credited with creating the first vaccine is Edward Jenner, an English scientist who pioneered one for smallpox in 1796. His breakthrough came from taking pus from a blister of someone infected with cowpox and using it to inoculate another person, thus preventing smallpox in that person. He developed this treatment after hypothesizing that dairy workers were rarely, if ever, infected with the deadly smallpox virus because most of them were already infected with cowpox, which has a very mild effect on humans.
So it’s kind of a complicated process, but here’s the two-sentence version: Lightning is an electric current that takes the path of least resistance from the base of a cloud to the ground. Since the air it travels through is not uniform—variations in things like temperature, humidity, and pollutants determine how resistant air is to the charge—the lightning has to zig and zag to stay on that path.
New Zealand and the islands of the Pacific are not considered part of a continent, but New Zealand is variously grouped (as is New Guinea) with the continent of Australia or with the larger conglomeration of Oceania, which, by definition, is not a geographical continent. New Zealand consists of two main and some smaller islands, and most of this territory sits on the Australian tectonic plate but straddles the plate boundary.Australia and Oceania are two completely different things. Australia (a continent) lies within the political region known as Oceania, which comprises also the islands of New Guinea, New Zealand and various other island nations in the South Pacific.New Zealand is the above-water part of a continental mass called Zealandia, about the size of India, and most of which has never been above the water's surface.Continents are defined by their landmass block, which is generally taken to be out to the edge of the Continental Shelf, where the contours drop off steeply to the abyssal deeps.
In a word, no, but scientists can make educated guesses. The closest living relatives of the dinosaurs are crocodilians and birds, and we can look to the ways they vocalize to give us a hint.Alligators and crocodiles use their larynxes to communicate—they’ll hiss, groan, and yes, roar (here’s a compilation of their sounds). Dinosaurs might have had larynxes, but since those don’t fossilize, it’s impossible to know for sure. Birds, meanwhile, use an organ called a syrinx, which seems to have evolved after dinosaurs. That might indicate that dinos couldn’t vocalize at all, which would be a bummer.However, there’s also a possibility that they evolved a unique way to vocalize. For example, based on studying their skulls and inner ears, some have theorized that hadrosaurs used their crests to bellow at each other.So, they probably didn’t roar, but bellowing can be pretty cool too, right?
There are many explanations offered for the origin of the name chickenpox:Samuel Johnson suggested that the disease was "less dangerous", thus a "chicken" version of the pox;the specks that appear looked as though the skin was pecked by chickens;the disease was named after chick peas, from a supposed similarity in size of the seed to the lesions;the term reflects a corruption of the Old English word giccin, which meant itching.
While organ music had appeared at hockey rinks in the 1930s, it first bellowed through a baseball stadium on April 26, 1941. Organist Ray Nelson played “classic and soulful compositions” before the Cubs took on the Cardinals at Wrigley Field. He had to stop before the game started, however, because he was playing copyrighted songs that could’ve been picked up by radio broadcasts.The baseball-stadium organ caught on quickly, however; the following season, the Brooklyn Dodgers hired a permanent organist, and their popularity increased through the mid-20th century. Nowadays, they’re commonplace.Oddly enough, the Cubs removed Nelson’s organ from the grandstand during a road trip shortly after it first appeared—the copyright liability was just too much for them—and organ music wouldn’t return to Wrigley until 1967.

I assume you’re referring to the difference between the glorious mustiness of a library and the glorious plasticy newness of a bookstore. That’s probably due to the fact that as paper ages, the cellulose within it decays, letting off that sweet, sweet book smell. Bookstore books haven’t had as much time to decay (unless it’s a used bookstore), leading to that different smell.
