You might have already noticed that every picture of iPhones on any advertisement has the time set at 9:41. But why is that? There is a cool story behind this. When Steve Jobs announced the first iPhone, the local time was 9:42 at that time in San Francisco, California. They knew that they will unveil the iPhone at 9:42 and set the time to 9:42 in the slideshow as well.

However, when the iPad was released, they announced it at 9:41. Since then, this is still in effect as of yet. So, whenever you see an iPhone in any advertisement, you will see the time is set at 9:41. And, it is not a coincidence at all. Now you know the story behind this as well.

During the first year of being in a romance, a protein in our cells called Nerve Growth Factor (NGF) that is vital for the functions of particular sympathetic and sensory nerve cells, appears to thrive. During youthful love, our senses are heightened, and our fight or flight reaction system is activated.

Seattle residents Peter Cicero and Richard Sclafani are credited with inventing the number-themed eyeglasses that are now seen at New Year's Eve parties around the world. According to the Wall Street Journal, their first set, which read "1991," sold 500 pairs. The following year, approximately 3000 sets were purchased.

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.

When explaining behaviour, we often attribute positive outcomes to internal factors and negative outcomes to external forces. When it comes to other people's actions, however, we usually attribute them to internal characteristics. For example, if we receive a poor grade on a paper, it is the fault of the teacher; if a classmate receives a poor grade, it is because he did not study diligently enough. The actor-observer bias refers to this tendency.

When you burp on Earth, gravity keeps the solids and liquids from the food you just ate at bay, allowing only the gas to leave your mouth. Because the gas cannot separate from the liquids and particles in the absence of gravity, burping effectively becomes vomit.

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?

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."

Scientists from the University of Birmingham investigated bikers aged 55 to 79 who ride their bikes for many hours each day. These researchers discovered that cycling in old age keeps muscle mass and strength from deteriorating. And the fat and cholesterol levels remained constant. However, the most incredible discovery is that cyclists' systems generate immunological T-cells in equal numbers to 20-year-olds. It's incredible since T-cell production begins to decline around the age of 20. This demonstrates that riding a bicycle makes the immune system younger.

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.

Being an astronaut is a serious profession, but they do allow for little fun every now and again. In space, "fun" activities, like as imbibing alcohol, are absolutely outlawed. However, astronauts have occasionally attempted to defy this regulation. Bottles of cognac have been "smuggled" into spacesuits by a few Russian cosmonauts. Smuggle because they couldn't lawfully transport the forbidden drug into space. They have acknowledged to mislabeling them as "juice bottles" or concealing them inside hollowed-out books. One determined astronaut concealed a little bottle in their blood pressure measurement device's wristband.

To obey authority figures, people will go to great, and sometimes dangerous, lengths. Stanley Milgram, a psychologist, discovered in his famous obedience experiments that people would be willing to deliver a potentially fatal electrical shock to another person if the experimenters ordered them to.

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.

Fetuses with short protuberances have been observed as early as 16 weeks of gestation. While there haven't been enough studies to determine why this happens, some point to the age-old "use it or lose it" theory—the Los Angeles Times reported that periodic movements are required to keep the penile tissue oxygenated and healthy.

The Salem witch trials took place between February 1692 and May 1693 in Salem, Massachusetts. Nearly 200 individuals, including the destitute, the elderly, and a four-year-old kid, were accused of witchcraft. The vast majority were imprisoned, and some were executed by hanging. However, none of these people were ever burned alive.

According to the World Health Organization, only Belarus consumes more alcohol than Moldova. With each person consuming an average of 16.8 litres of liquor each year (excluding under 15s). Well that is a lot of booze..

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.

In another University of Pennsylvania research, one group learnt about a starving small child, another about millions dying of hunger, and a third about both conditions. People gave more than twice as much money when they heard about the little girl as when they heard the statistics—and even those who heard her tale in the context of the larger tragedy gave less. Psychologists believe that we are predisposed to help the person in front of us, but when the situation feels too vast, we believe that our small contribution is insignificant.

When it comes to the content of their dreams, researchers discovered some differences between men and women. In several studies, men reported dreaming about weapons significantly more frequently than women, while women dreamed about clothing references more frequently than men. Women have slightly longer dreams with more characters than men. When it comes to the characters that appear in dreams, men dream about other men twice as often as women, while women dream about both sexes equally.

We frequently predict how we will react to a future event, only to find out that we reacted completely differently than we anticipated. We put our faith in the ability of a single event to change everything, but we frequently discover that it has little effect on how we feel.

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?

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.

Einstein was leaving a ceremony in his honour on his 72nd birthday. Photographers begged him to grin for the camera as he was getting into his car. Einstein, on the other hand, was weary of smiling for photos—he'd be doing it all evening—so he stuck his tongue out instead. Einstein was so taken with the photograph that he had it printed as greeting cards.

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.

Obviously, James Bond is a British legend, yet he is of Scottish heritage. This is particularly evident in films like Skyfall, in which Bond returns to his childhood home in Scotland. However, Bond's lineage was not revealed until later in the series. Following the popularity of Dr. No, which starred Sean Connery as the famous spy, Ian Fleming incorporated Bond's Scottish origin. Of course, Connery is Scottish. Fleming specifically included these Scottish facts in the 007 novel You Only Live Twice, eternally establishing Bond's background. Connery would subsequently feature in the cinematic version of the book, however it was hardly faithful to the source material.
