A shock wave can be produced by sound. Sharp and repetitive sounds, such as drumming, can cause shock waves when an object vibrates at a high pace. A shock wave is produced by a loud bang or clap. While a shock wave caused by a clap is harmless, a shock wave caused by an explosion is deadly since it can kill many people.

Small amounts of sun exposure — 10 to 20 minutes is ideal — can be beneficial for acne. Excessive sun exposure, on the other hand, can aggravate existing acne scars and cause new breakouts.

Jim Shooter, Marvel's editor-in-chief at the time, was approached by the head of Warner Communications' publishing but declined the offer, arguing that DC characters wouldn't sell since they weren't very good. Ouch! Consider what would happen if the deal went through. That old Marvel vs. DC comics dispute would not have occurred!

Despite weighing just 20 pounds on average, these creatures can apply up to 94 pounds of pressure, giving them a "Bite Force Quotient" of 181. That's about twice as powerful as a hyena and 60 points stronger than a lion.

We say "cheese" because it makes us happy, but if Victorian-era people saw our delighted grins, they'd laugh. Smiling in pictures was once considered demeaning and reserved for the impoverished and inebriated. To maintain a more serious appearance in their photographs, they would utter "prunes," a word so uninteresting that the odds of it eliciting a grin were minimal to none.

They were eventually discovered to be S.H.I.E.L.D. agents. They went on several missions together and even helped Wolverine out of a jam at one time. Unfortunately, they were killed in an aircraft crash engineered by the nefarious Red Skull not long after giving birth to Peter.

The fundamental technology behind windmills was undoubtedly derived from the wind sails that were used to steer ships. However, the first instance of wind energy being used to help automate routine manual tasks, such as pumping water or grinding grain, was most likely in Persia. Last but not least, the first vertical axis windmill design that has been historically recorded is the Persian panemone windmill, with records of the technology dating back as far as 1,500 years. The vertical sail on this particular specimen was made of bundles of reeds or wood, which were then fastened to the central vertical shaft with the aid of horizontal struts.

With tremendous reverence, I bow before the sun, who moves 2,202 yojanas in half a nimesha, stated Sayana, a 14th-century Vedic scholar. A yojana is 9 miles long, whereas a nimesha is 16/75 of a second. As a result, 2,202 yojanas multiplied by 9 miles multiplied by 75/8 names equals 185,794 miles per second or 2,99,000 kilometers per second. That is amazingly close to the true scientifically confirmed' speed of 3,00,000 kilometers per second. It is commonly assumed that his source was none other than the Vedas.

In Greenland, 11% of the population is not Inuit. As a result, any Inuk who lives in Greenland has the opportunity to have new dining experiences, however even this hasn't significantly changed their traditional diet.

When he was finally caught and his house of horrors in Plainfield, Wisconsin, discovered, police found masks and lampshades made from human skin, among plenty of other atrocities. His astonishing depravity proved a source of creative inspiration.

Italian scientists and researchers have recently been able to conduct CT scans of the bodies interred at Pompeii thanks to recent technological advancements. One of the most intriguing things they have revealed is that Pompeii's inhabitants had white, straight teeth.
