Stringed instruments, such as the violin, have a series of stretched strings on them. When you press down on one of the strings, its length changes and it vibrates at different frequencies, producing varied sounds. A brief stroke on a metallic string produces a loud sound, whereas a long stroke produces mellow music. The thickness of the string is also important, as it controls the strength of the sound.

A fun fact about Spanish is the second language in the world with more native speakers. It comes right after Chinese and right before English. Spanish was born in Spain, but today it is spoken throughout the American continent and in some places in Africa and Asia.

Antibiotics can be useful in eradicating H. pylori when it does result in an ulcer.

A common, but the lesser-known side effect of anxiety is anger. When we feel powerless over a situation, or our life is out of our control, expressing anger is a natural way to feel a sense of control.
It’s much easier to externalize the conflict rather than acknowledge the real issue and deal with it. Additionally, with chronic sufferers of anxiety, depression sometimes develops.

Excessive exfoliation and cleansing can aggravate your acne problems. It irritates and dries out your skin, causing it to produce more oil. Excessive use of acne treatments can have the same effect. Stick to a morning and evening routine that includes cleansing, medicating, and moisturising.

The Sun appears to have existed in perpetuity, unchanged, but this is not the case. The Sun is gradually heating up. Every billion years, it becomes 10% more luminous. In fact, within a billion years, the Sun's heat will be so intense that liquid water will no longer exist on Earth's surface. Life on Earth as we know it will cease to exist. Bacteria may still exist underground, but the planet's surface will be scorched and uninhabitable. It will take another 7 billion years for the Sun to reach its red giant phase, at which point it will engulf the Earth and destroy it entirely.

The risk of heart disease and stroke can rise when one breathes in contaminated air. It aggravates asthma symptoms and even has been linked to lung cancer. We are urging the government to phase out diesel vehicles by 2025 as a starting step in addressing this. The human costs of both indoor and outdoor air pollution are horrendous; air pollution is a factor in millions of preventable deaths each year.

When luciferase was first discovered, fireflies were the only source of the chemical. Even though synthetic luciferase is now readily available, some businesses continue to collect fireflies, which may be a factor in their decline.

The fate of the Afrikaans language was a hot topic during negotiations for South Africa's new government in 1992. The ANC sought to make English the official language of the nation, but Afrikaner nationalists were anxious that it remains on par with English. The ANC concurred, but it was difficult for them to justify simply adopting Afrikaans and leaving out other indigenous languages. Then came South Africa's inclusive linguistic policy.

Libya imports the majority of the food it consumes due to its inability to produce it locally. Because the nation is located within the vast Sahara desert, it receives extremely little precipitation. It also has weak soil and a harsh climate, both of which hinder food production. The financing of the Great Manmade River Project, which was designed to irrigate farmed fields, was a major attempt by former Libyan President Gaddafi to reverse the situation. This project ended up becoming the largest irrigation project in the world. It consists of a 1750-mile subterranean water pipe network. Libya's people, meanwhile, continue to rely on imported food to survive.

Kakapo is the only flightless parrot in the world. But that’s not the only interesting fact about the world’s largest parrot. Kakapo is also the only parrot that is active at night.

With the fall of the Roman Empire, the secret of making Greek Fire was lost. Throwing water on it would simply feed the flames, making this weapon one-of-a-kind and lethal. It had a gelatinous feel and stuck to everything. It was largely utilised in naval warfare since the huge flamethrowers required for its projectile usage could be handled easier by ships than troops. A fleet of floating wood and canvas ships would be readily destroyed by the Greek Fire.

San Marino is the world's fifth-smallest country, behind Monaco, the Vatican city-states, and the island countries of Tuvalu and Nauru. San Marino has a population of 33,562 people and a land area of slightly more than 61 km2 (24 sq mi).

Just as there was a run on pet rats, the population of clownfish in their natural habitats took a precipitous drop following the release of Finding Nemo, which stars a clownfish.

The album, which was released in 1945, included the titular Bunk on trumpet as well as an alto horn, bass horn, baritone horn, snare drum, and bass drum. The band is "so out of tune that it makes the music difficult to listen to," according to Jazz on Record. Thankfully, Bunk Johnson and his band significantly improved on subsequent albums, and the New Orleans brass band tradition is still alive and well today.

Meat-inspired perfumes are more common than you might guess. While definitely not gourmands, these scents are still weirdly food-like. Que Cologne from Pork Barrel BBQ is described by the brand as a mix of smoke, meat, spices, and "sweet summer sweat", and there is a perfume called Bacon Classic that smells exactly like fried and salty pig mixed with cedar, orange, and pepper.
Wild, right?

Fewer than two in ten chief financial officers in the 350 largest British PLCs are women, only 4% of investment managers are women, and only 5% of corporations are led by a female CEO. There are more CEOs named Peter in the FTSE 100 than there are female CEOs. According to Lean In and McKinsey's 2020 Women in the Workplace report, which reviewed data from 329 firms, while entry-level roles are virtually evenly divided between genders, the ratio of women drops by roughly half at the senior VP level. Women make up nearly half of the workforce but hold just 38% of managerial roles, with the percentage decreasing with each additional level of seniority.
