Sound waves can be recorded and transmitted to a digital signal, which has a specific pattern of the required sound waves in a digital series that can be stored on a digital tape, CD, or computer system. When you play the signal, the digital pattern is converted back into sound waves. Although analogue sound recordings produce an exact copy of the desired sound wave pattern, making many copies of the original records can introduce extra noise and distort the unique pattern. However, digital records only have a pattern of numbers that you may replicate and correct as needed without any distortion. As a result, digital sound recording is always preferable to analogue recording.

This fun fact about the Netherlands may entice beer-lovers to visit – they have the largest pub in all of Europe. 

The Drie Gezusters (Three Sisters) pub in Groningen holds the title of the biggest pub on the continent and is a national heritage site. We hope it’s also got the most bathrooms of all the pubs in Europe!

 

Due of their importance to the health of our seas, this marine mammal is both intriguing and unjustly underappreciated. Although there are still plenty of krill, the population is anticipated to suffer as a result of climate change as ice melts and elevates the level of water.

The coconut tree can reach a height of 82 feet (25 metres). Coconut trees can flower up to 13 times each year, yielding up to 65-75 fruits per year.

Did you think it took a long time for clothes to decompose? Shoes are even more time consuming! The midsoles of shoes, which are commonly made with ethylene vinyl, can take a long time to degrade. Rather than adding to landfills, consider donating or selling your shoes!

Maxwell Lappe, a dentist, invented Nu Nails, an artificial nail designed specifically for nail biters, in 1934. Dentists must be obsessed with nail care, because dentist Fred Slack invented the first modern acrylic nails.

The Taj Mahal is almost perfectly symmetrical, in keeping with Persian and Islamic architectural principles. The minarets (towers), walls, rooms, and even gardens are all symmetrical. The Taj Mahal, one of the world's most perfectly symmetrical structures, is known for its white beauty and sheen. The placement of Shah Jahan's cenotaph — and his grave — are possibly the only elements of the Taj that do not adhere to perfect geometric proportions and symmetrical precision.

Thyme needs to be kept out of heat, moisture, and sunshine in an airtight container. Make sure the spices stay cool; keep them away from any outside walls to prevent them from being exposed to the daylong, sweltering summer sun (even light can affect dried herbs).

Finding previously unknown organisms in the depths of the ocean may sound like something out of a science fiction horror film, but a 2020 study of a deep-sea volcano near New Zealand, published in the Proceedings of the National Academy of Sciences of the United States of America, uncovered "over 90 putative bacterial and archaeal genomic families and nearly 300 previously unknown genera." Hydrothermal vents, like deep-sea volcanoes, have been connected to the "beginning of life" in certain studies. So, are we seeing the beginnings of future land-dwellers? We'll have to wait and see what happens.

Another interesting fact about Egypt is that Cleopatra, one of the most famous figures from ancient Egypt, is actually Greek, not Egyptian. While she was born in Alexandria she had no Egyptian blood and was instead a descendant of the Ptolemaic Dynasty which were a line of Greek Macedonians. The Ptolemaic Dynasty ruled ancient Egypt from 323 to 30 BC. The name Cleopatra is actually Greek for “Famous in Her Father” or “Her Father’s Fame”

Do you think anglerfish and other bioluminescent critters are cool? You, too, light in a similar process known as biophoton emission. Scientists have been able to record minuscule quantities of light emitted by chemical processes in our cells using ultra-sensitive cameras. The glow, however, cannot be seen with the naked eye since it is a thousand times dimmer than what humans can perceive.

More than half of the 5.4 million Americans who have Alzheimer's disease are unaware that they have it. This Alzheimer's fact may seem unlikely, but it is mostly a result of the difficulties in diagnosing early-stage Alzheimer's, which leaves many instances misdiagnosed.

The Journal of Experimental Psychology published a study in January 2014 that found babies as young as nine months old recognise that their friends have similar interests.

The Vatican Advanced Technology Telescope was bought by the Vatican in 1981. It is one of the world's biggest telescopes. It is located on the summit of Mount Graham in southeast Arizona, and it is where the Vatican performs astronomical research.

The man responsible for the creation of arguably the most well-known cartoon character in the world, Mickey Mouse, was afraid of mice! Does it get any more ironic? Walt Disney had a deep-seated fear of the four-legged creatures. But he also saw them as sympathetic. That was why he choose to base Mickey on a mouse. It turned out to be a solid decision from Disney. Mickey Mouse helped turn Disney into one of the world’s biggest entertainment companies. 

By drumming and fluttering their pointed appendages, crabs produce sounds that can only be described as crustacean Morse code. Some crab species have a particularly big claw that is utilised for communicating.

Seeing new individuals nude isn't as fascinating as it sounds after time. The sight of another body does not excite most OB-GYNs. "Over time, that perspective shifts from sexual to therapeutic. I know many patients don't notice a change, but I get a little weirded out when individuals just strip naked in front of me "according to one doctor

The majority of samhainophobic readers are probably not viewing this slideshow due to their fear of Halloween. Despite the fact that many patients realise there is no real threat, October 31 still causes them anxiety. Samhainophobia can include fears of ghosts, witchcraft, and darkness.

Anyone who visits Myanmar will notice people in the streets with what seems like mud smeared over their faces. This is a little disconcerting at first but it’s nothing to worry about.

Actually, it’s a special mixture of powdered bark that comes from a particular tree. When it’s produced, locals wipe it on their faces to act as protection against the sun.

Eczema comes in a variety of forms, and each person is affected by it differently. A qualified diagnosis can guarantee that your course of treatment corresponds to your particular symptoms.

More than 40% of new cars sold in the UK now are diesel, up from 13% or so a little more than ten years ago. In the UK, there are currently 12 million diesel vehicles on the road. Government incentives based on the lower carbon emissions and higher fuel economy of diesel compared to gasoline are mostly to blame for this. Diesel vehicles produce significantly more dangerous NOx than their petrol-powered counterparts.

Charlotte and Emily left the parsonage in 1842 to go to the Pensionnat Héger in Brussels, Belgium.
