Valentina Vladimirovna Leonid Ilych Brezhnev, first secretary of the Soviet Communist Party since , is elected president of the Supreme Soviet, thereby becoming both head of party and head of state. On June 16, , newly nominated senatorial candidate Abraham Lincoln addresses the Illinois Republican Convention in Springfield and warns that the nation faces a crisis that could destroy the Union.
Speaking to more than 1, delegates in an ominous tone, Lincoln paraphrased Paul, Minnesota. Soliah, who now calls herself Sara Jane Olson, had been evading authorities for more than 20 years.

Several years earlier he had ridden on the Mauch Chuk Switchback Railway in Pennsylvania, a former mine track used to transport coal down a mountainside that had become a popular tourist attraction. It was the first bona fide roller coaster to be built in the US, shaped like the early Russian ice slides two hills parallel to each other , incorporating undulating hills and a flat steel track nailed onto several layers of wooden plank, connected to two 45 foot towers.
The maximum speed was 6 mph, and the cars had to be manually towed to the top of the hills at the start of both tracks. Nevertheless, the ride was an instant success with the public. Within four years, Thompson had built approximately 50 more coasters across the nation and in Europe, and then began work on what became his most famous attraction, the Scenic Railway, designed with James A.
It opened in in Atlantic City and featured artificial scenery illuminated by lights triggered by the approaching cars—a precursor to the elaborate theme park rides at Disneyland and other parks today. Of course, Thompson was not the only early designer of roller coasters, either in the US or abroad, and improvements and innovations were quickly made.
In , Charles Alcoke designed a coaster with a continuous track, so that the ride ended where it began, and the following year Phillips Hinckle used a mechanical hoist to raise the cars to the top of the hill, rather than being towed manually. That same year saw the debut of the first experiment with loops with the Flip Flap, which rolled cars through a 25 foot diameter circular loop, but closed in because of the frequent neck and back injuries suffered by its passengers.
By the end of the 19th century, all the basic elements of the modern roller coaster were in place, although they were slow. This baby goes from zero to miles per hour in just 4. When it opened on August 1, , the Steel Dragon was the fastest, tallest and longest in the world. Others have stolen the fastest and tallest crowns, but the Dragon is still the longest. And what will you be doing in that time? After the chain lift hill is an initial drop of The train subsequently rises up and into the figure-eight shaped helix.
The train then passes through a mid-course brake run and over six more camelback hills, passing through two tunnels along the way before reaching the final brakes. The moment lives on as a single sentence in his Wikipedia page—and several other blog posts. Higher levels of dopamine, which are neurotransmitters associated with reward-motivated behavior, are linked to sensation-seeking activities.
Another study that focused on bungee jumpers found that higher levels of endorphins led to increased feelings of euphoria, which would explain why some people dig the thrill so much. Roller coasters of the future are bound to be wild.
