Stelele neutronice sunt probabil cele mai exotice obiecte din Univers. Acestea sunt "excesive" aproape în toate aspectele: gravitaţie, tăria câmpului magnetic, densitate şi temperatură. Aţi putea spune că găurile negre sunt mai dense şi într-un anumit sens ar fi adevărat, dar, în fapt, noi nu putem determina structura interioară a unei găuri negre, care este definitiv ascunsă dincolo deorizontul evenimentelor.

Fun Dog Facts for Kids

Enjoy these fun dog facts that deliver a variety of information about interesting breeds, puppies, guide dogs such as Labradors and much more. As the famous saying goes, dogs are man’s best friend. Whether it’s as reliable workers, family pets or loyal companions, dogs are wonderful domestic animals that offer a number of qualities that are put to good use by humans.

 

 

In total there is said to be around 400 million dogs in the world.

The domestic dog has been one of the most popular working and companion animals throughout human history.

Dogs perform many useful tasks for humans including hunting, farm work and security as well as assisting those with disabilities such as the blind.

Although experts often disagree, there is scientific evidence which shows that the domestication of dogs could have occurred more than 15,000 years ago.

There are hundreds of different breeds of dogs.

Examples of these breeds include: Bulldog, German Shepherd, Collie, Golden Retriever, St Bernard, Greyhound, Bloodhound, Chihuahua, Labrador, Great Dane, Rottweiler, Boxer and Cocker Spaniel.

The most popular breed of dog in the world by registered ownership is the Labrador. With their gentle nature, obedience, intelligence and near limitless energy, Labradors make for excellent family pets and reliable workers. They often assist police and are a common choice as guide dogs.

Dogs have formed such a strong bond as pets, workers and companions to humans that they have earned the nickname "man's best friend".

Humans help train various dog breeds to enter in competitions such as breed shows, agility and obedience contests, racing and sled pulling.

Dog have superior hearing than humans, capable of hearing sounds at four times the distance.

Dogs have a remarkable sense of smell, they are capable of differentiating odors in concentrations nearly 100 million times lower than humans can.

The average life span for a dog is around 10 to 14 years.

Those involved in dog breeding refer to males as ‘dogs’, females as ‘bitches’, dogs younger than a year old as ‘puppies’ and a group of offspring as a ‘litter’.

Domestic dogs are omnivores, they feed on a variety of foods including grains, vegetables and meats.

This week is National Chemistry Week and in honor of our beloved Chem nerds, here are 25 weird chemistry facts you probably didn’t know.

Today is Mole Day. Every year on October 23 from 6:02am to 6:02pm, chemistry students and chemists celebrate Mole Day in honor of Avogadro’s number, the number of carbon atoms in 12grams of carbon.

There is about 1/2lb or 250g of table salt (NaCl) in the body of an average adult human.

Lightning strikes produce ozone (O3) and help strengthen the ozone layer.

Humans have been using chemistry since at least Ancient Egypt. By 1000 bce human civilizations were using advanced forms of chemistry like extracting metals from ore, fermenting alcohol, and refining plant extracts as medicine.

DNA is flame retardant.

One bucketful of water contains more atoms than the Atlantic Ocean does bucketfuls of water.

If you slowly pour a handful of salt into a completely full glass of water, it will not overflow. In fact, the water level will go down.

Although oxygen gas is colorless (light refraction aside), both the liquid and solid forms are blue.

One inch of rain is equal to 10 inches of snow.

You have chemoreceptors (taste buds) on the inside of your cheeks too.

Hydrofluoric acid is so corrosive that it will dissolve glass. Although it is corrosive, hydrofluoric acid is considered to be a ‘weak acid’.

Approximately 20% of the oxygen in the atmosphere was produced by the Amazonian rainforests.

The only elements that are liquid at room temperature are bromine and mercury.

Though solid at room temperature, gallium will liquefy in your hand.

Hydrogen is the most abundant element. About 75% of the elemental mass of the universe is hydrogen.

The most common isotope of hydrogen is protium, with is 1 proton and 0 neutrons.

The hardest chemical in your body is your tooth enamel.

The ethylene gas produced by ripening fruit, ripens other fruit and vegetables.

The only letter that doesn’t appear on the Periodic Table of Elements is J.

The human body contains enough carbon to produce graphite for about 9,000 pencils.

If you expose a glass of water to space, it will boil rather than freeze. The water vapor would almost immediately crystallize into ice.

Oxygen is the most abundant element in the Earth’s crust, water, and atmosphere.

Bee stings are acidic while wasp stings are alkaline.

Mosquitoes like the scent of estrogen, thus women get bitten more often than men do.

The lighter was invented before the match.

And what list is complete without one silly joke? Billy was a chemist’s son but now he is no more, what he thought was H2O was H2SO4!

10 Facts About the Titanic That You Don't Know

Canceled Lifeboat Drill
Originally, a lifeboat drill was scheduled to take place on board the Titanic on April 14, 1912 - the day the Titanic hit the iceberg. However, for an unknown reason, Captain Smith canceled the drill. Many believe that had the drill taken place, more lives could have been saved.

Only Seconds
From the time the lookouts sounded the alert, the officers on the bridge had only 37 seconds to react before the Titanic hit the iceberg. In that time, First Officer Murdoch ordered "hard a-starboard" (which turned the ship to port -- left). He also ordered the engine room to put the engines in reverse. The Titanic did bank left, but it wasn't quite enough.

The Titanic's Newspaper
The Titanic seemed to have everything on board, including its own newspaper. TheAtlantic Daily Bulletin was printed every day on board the Titanic. The newspaper included news, advertisements, stock prices, horse-racing results, society gossip, and the day's menu.

Lifeboats Not Full
Not only were there not enough lifeboats to save everyone on board, most of the lifeboats that were launched off the Titanic were not filled to capacity. For instance, the first lifeboat to launch, Lifeboat 7 from the starboard side, only carried 24 people, despite having a capacity of 65 (two additional people later transferred to Lifeboat 7 from Lifeboat 5). However, it was Lifeboat 1 that carried the fewest people - only seven crew and five passengers (a total of 12 people) despite having a capacity for 40.

Only Two Bathtubs
Although most passengers had to share bathrooms (only the two promenade suites in first class had private bathrooms), third class had it rough with only two bathtubs for more than 700 passengers.

Another Boat Was Closer for Rescue
When the Titanic began sending out distress signals, the Californian, rather than theCarpathia, was the closest ship; yet theCalifornian did not respond until it was much too late to help. At 12:45 a.m. on April 15, 1912, crew members on the Californian saw mysterious lights in the sky (the distress flares sent up from the Titanic) and woke up their captain to tell him about it. Unfortunately, the captain issued no orders. Since the ship's wireless operator had already gone to bed, the Californian was unaware of any distress signals from the Titanic until the morning, but by then the Carpathia had already picked up all the survivors. Many people believe that if the Californian had responded to the Titanic's pleas for help, many more lives could have been saved.

Two Dogs Rescued
With the order for women and children first into the lifeboats, plus the knowledge that there were not enough lifeboats for everyone on board the Titanic to be saved, it is a bit surprising that two dogs made it into the lifeboats. Of the nine dogs on board the Titanic, the two that were rescued were a Pomeranian and a Pekinese.

The Fourth Funnel
In what is now an iconic image, the side view of the Titanic clearly shows four cream and black funnels. While three of these released the steam from the boilers, the fourth was just for show. The designers thought the ship would look more impressive with four funnels rather than three.

A Royal Mail Ship
The R.M.S. Titanic was a Royal Mail Ship, a designation which meant the Titanic was officially responsible for delivering mail for the British postal service. On board the Titanicwas a Sea Post Office with five mail clerks (two British and three American). These mail clerks were responsible for the 3,423 sacks of mail (seven million individual pieces of mail) on board the Titanic. Interestingly, although no mail has yet been recovered from the wreck of the Titanic, if it were, the U.S. Postal Service would still try to deliver it (the USPS because most of the mail was being sent to the U.S.).

Corpses Recovered
On April 17, 1912, the day before survivors of the Titanic disaster reached New York, theMackay-Bennett was sent off from Halifax, Nova Scotia to search for bodies. On board theMackay-Bennett were embalming supplies, 40 embalmers, tons of ice, and 100 coffins. Although the Mackay-Bennett found 306 bodies, 116 of these were too badly damaged to take all the way back to shore. Attempts were made to identify each body found. Additional ships were also sent out to look for bodies. In all, 328 bodies were found, but 119 of these were badly damaged and thus were buried at sea.
