On January 28, 1896, Arnold was caught driving four times the speed limit in his 19th-century Benz—but because the speed limit at the time was only two miles per hour, he wasn't travelling too fast by today's standards. The officer had to track him down on his bike, issuing a £4 7s penalty and earning Arnold the swift distinction.

Do you consider all of your decisions, weighing all of your options and calculating the impact of each outcome? You may believe you are, but you are incorrect. The majority of your decisions are made subconsciously because your conscious mind would be overwhelmed with information and you would likely become mentally frozen. This is because your brain receives over 11 million bits of information every second, and there simply isn't enough "brainpower" to process it all consciously.

Why doesn't your stomach digest itself if it has so many enzymes and acids that it can digest a piece of meat? It turns out that it sort of does.

Poland has been manufacturing the popular drink since the Middle Ages, and the Polish still produce some of the greatest vodkas in the world, generating over 260 million litres of it each year.

The notion that Einstein struggled at school is a fiction. A pre-teen Einstein would study mathematics and physics for fun over the summers, finally mastering differential and integral calculus by the age of 15. But it doesn't mean he was a model student. Einstein despised rote learning and refused to study things that bore him. As a result, when the stubborn number-lover took the polytechnic school admission exam in Zurich, he flunked the language, zoology, and botany parts.

Despite the fact that he is a fictitious character, Bruce Wayne has a higher IQ than Albert Einstein! Einstein's IQ was estimated to be between 160 and 180, while Bruce's is 192!

It doesn't seem to matter what others say about a new lover—in our eyes, he or she is always ideal. This blindness is essential for us to progress in our relationship.

The "Pygmalion effect" or "Rosenthal effect" refers to the phenomenon that higher expectations can increase performance. Professor Robert Rosenthal was the first to demonstrate it. In a California elementary school, he conducted an experiment and discovered that when teachers are made aware of students who have a high chance of success, their expectations rise. As a result, they paid special attention to those students and sometimes treated them differently. Essentially, the teachers subconsciously acted differently toward those students, which promotes their success. This has a positive impact on the student, and their performance improves as a result.

Apart from  butter-fingers, crossfire, dustbin, fairy story, slow-coach and whoosh, Charles Dickens is also credited with coining the term "boredom" in the Oxford English Dictionary, which he used in his novel Bleak House (1852-3), but this has since been traced back even further, to 1830.

People tend to seek out information that confirms their existing beliefs while ignoring information that contradicts their existing beliefs. This is referred to as confirmation of expectations.

Scientists can detect whether a gene has been effectively inserted into an animal's DNA by adding some type of clearly recognised marker to it. When testing an anti-FIV gene in 2011, scientists at the Mayo Clinic employed a fluorescent protein from a particular jellyfish. The tests were successful, however the cats did glow in the dark. In fact, these cats' offspring sparkle in the dark! Nonetheless, their accomplishment is only one step toward an ultimate solution for AIDS.

Visit the iconic Kaminarimon temple, albeit you may have to compete with other eager tourists!

Apple actually approached Verizon to collaborate in the making of the iPhone. However, Verizon had some conditions that were not liked by Apple. Thus they reached out to ‘Cingular Wireless’(AT&T Mobility)with the proposal. And, both parties agreed to all the terms and conditions and started to work on the project secretively. After working for over 2 and a half years, Apple unveiled the iPhone. The estimated development cost of the iPhone was about 150 million USD.

If you want to do something creative, such as write a short story or design a dress, do it after a long and stressful day. This is because studies have shown that when people's brains aren't functioning as well as they should, they become more creative.
