Recently, SpaceX sent four passengers into Earth orbit aboard the Crew Dragon spaceship. A concept for an aeroplane dubbed Rukma Vimana may be found in the book Vaimanika Shastra. G. R. Josyer disclosed the book in 1952, claiming that it was authored by Pandit Subbaraya Shastry (1866–1940), who dictated it between 1918 and 1923. In 1957, the first spacecraft was launched. Looking at the images above, you can see how similar these designs are. So, how did a Pandit in India envisage the concept of a spaceship 34 years before the first spacecraft launched? Is it just a coincidence?

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. It contributes significantly to confirmation bias, a type of cognitive bias. This desire for confirmation causes us to avoid information that challenges our worldview.

Austrians celebrated their victory over Hungary during the 1848 revolution by clinking their drinks during a toast. Since then, Hungarians have avoided clinking their glasses while toasting since it reminds them of their loss. Instead, if you're drinking a beer in Hungary, say "Egészségedre" while looking your drinking companions in the eyes.

The date of February 14 was formally named "St. Valentine's Day" by Roman Pope Gelasius around the end of the fifth century. However, it wasn't until the Middle Ages that the festival became connected with love and passion, a tradition that sprang from the widespread belief in France and England that birds began their mating season on February 14.

This occurred while he was shooting "127 Hours." According to legend, Franco enrolled in an NYU acting class where the teacher gave him a "D." He was working 127 hours at the time. Another aspect of this incident is that the professor was eventually sacked for assigning a "D" grade to Franco's paper.

Traditionally, Russia was Moldova's largest export market, consuming up to 90% of its wine. However, a diplomatic conflict in 2006 resulted in a Russian ban on Moldovan and Georgian products, which has proved disastrous to the economies of both countries. Nonetheless, it is the world's 20th largest wine-producing country (as of 2014).

Russians are divided on this truth regarding Poland, however it is widely assumed that vodka was developed in Poland. The spirit was first mentioned in recorded form in Polish court papers in 1405, and it was first utilised as medication. 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.

This curiosity has a social explanation rather than a scientific one. For centuries, society and the media have pushed women to hold themselves to a certain standard, whether it's small feet or a perky behind, and the majority of women have chosen stylish presentation over comfort.

Life is a difficult and dirty affair. If you don't want to lose brain cells, you might want to skip this calorie-burning tip. A 45-minute stroll with your dog would be a safer method to burn 150 calories.

According to research, our brain can only keep 3-4 pieces of information at a time. Furthermore, this data can only be saved for 20-30 seconds. We forget it after this period unless we keep renewing it in our minds over and again. For example, you are driving while chatting on the phone (do not do this!). The person on the other end of the line gives you a number, but you can't write it down, so you memorize it. You repeat the number several times to keep it in your short-term memory until you disconnect and write it down.

On Mondays, the chance of suffering a heart attack rises by 20% for men and 15% for women. It's most likely due to the stress of having to return to work. However, scientists caution that alcohol drank over the weekend can potentially be a cause of a heart attack.

Speaking of astronauts, their experience has shown that transitioning from weightlessness to gravity can be taxing on the body. Muscles atrophy and bones lose bone mass in the absence of gravity. According to NASA, astronauts in space can lose 1% of their bone mass per month.

Ancient Egyptians regarded cats to be sacred creatures. Most households are said to have kept a cat as a pet because they felt it would bring them good luck!

It may be difficult to believe, but we have roughly the same number of hairs on our bodies as chimps; the difference is that our hairs are useless, being so fine that they are almost invisible. We're not sure why we lost our furry protection. It has been proposed that this was done to help early humans sweat more easily, to make life more difficult for parasites like lice and ticks, or even because our ancestors were partially aquatic.

If you're familiar with Spider-Man, you'll know that one of his most potent talents is his renowned Spider Sense. This heightened sense had alerted him of impending threats and had saved his life several times. His spidey sense was always on and practically hard to avoid. It was unaffected by darkness or blindness. That alone makes it incredible, but it is far more potent than you may expect. It alerted him of existential hazards to his well-being in addition to acute bodily concerns. It would even warn him to any possible witnesses when he changed his outfit, for example.

Now, before you start freaking out, please hear us out! Sedentism is encouraged in today's environment. After all, we sit during our commutes, to eat, to watch TV, to work, to socialise with our friends, and so on. It turns out that even if you exercise regularly, it won't keep you safe from the risks of the "office lifestyle."

Martin Lotze, a German researcher, studied the brains of both professional athletes and professional writers and discovered that their brain activity during athletic competition and the writing process was very similar. Lotze discovered an interesting difference between professional and amateur writers: professional writers used their speech-processing centres of the brain to develop their stories, whereas amateur writers relied on their vision centres to imagine the story first.

Everyone has experienced the agony of rejection at some point in their lives, but did you know that rejection causes physical harm as well as emotional pain? Even if you are unable to feel physical pain, scientists have discovered that the reactions and cascading events that occur in the brain after rejection or physical pain are nearly identical. Furthermore, the same natural chemical is released in both cases.

For millions of people, the coffee break is an important but often overlooked part of their day. The town of Stoughton, Wisconsin, hosts an annual Coffee Break Festival to pause and honour the break. There will be coffee tastings, "brew-offs," and bean-spitting contests at the event. What makes Stoughton unique? According to city officials, the coffee break "was born" in the city in the late 1800s, when women working at the local Gunderson Tobacco Warehouse started the ritual of pausing during the workday to brew some coffee and chat.

Tooth decay occurs when bacteria in your mouth convert sugar into acids, further eroding the tooth's surface and causing cavities. Cocoa beans contain antibacterial agents that inhibit the growth of these bacteria and help to prevent tooth decay. Dark chocolate contains more cocoa than milk chocolate. However, this does not imply that you consume chocolate on a daily basis.

This study was inspired by evidence obtained from wrongful conviction cases. The study involved interviewing adult suspects in a comfortable setting and employing poor memory retrieval techniques. Within three hours, the suspects had been interrogated in ways that led them to believe in and confess to crimes they had not committed. They were even able to vividly describe the events, and some of them believed they had committed a crime as serious as assault with a weapon as teenagers. Are you willing to be persuaded?

People who have a full bladder are more convincing liars. A strong urge to use the restroom causes a person to focus on self-control, making lying more plausible. Furthermore, they attempt to prevent unnecessary movement. That's why scientists conducting a scientific experiment believed liars who needed to go to the bathroom.

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. The cells that line your stomach proliferate fast in order to replace the cells that are killed in the course of their everyday tasks. Every three days, we develop a new gut lining.
