Albert Einstein - Biography:

1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect" (from the official Nobel Prize announcement)

Albert Einstein - Early Work:

In 1901, Albert Einstein received his diploma as a teacher of physics and mathematics.

Unable to find a teaching position, he went to work for the Swiss Patent Office. He obtained his doctoral degree in 1905, the same year he published four significant papers, introducing the concepts of special relativity and the photon theory of light.

Albert Einstein & Scientific Revolution:

Albert Einstein's work in 1905 shook the world of physics. In his explanation of the photoelectric effect, he introduced the photon theory of light. In his paper "On the Electrodynamics of Moving Bodies," he introduced the concepts of special relativity.

Einstein spent the rest of his life and career dealing with the consequences of these concepts, both by developing general relativity and by questioning the field of quantum physics on the principle that it was "spooky action at a distance."

In addition, another of his 1905 papers focused on an explanation of Brownian motion, observed when particles seem to randomly move when suspended in a liquid or gas.

His use of statistical methods implicitly assumed that the liquid or gas was composed of smaller particles, and thus provided evidence in support of the modern form of atomism. Prior to this, though the concept was sometimes useful, most scientists viewed these atoms as merely hypothetical mathematical constructs rather than actual physical objects.

Albert Einstein Moves to America:

In 1933, Albert Einstein renounced his German citizenship and moved to America, where he took a post at the Institute for Advanced Study in Princeton, New Jersey, as a Professor of Theoretical Physics. He gained American citizenship in 1940.

He was offered the first presidency of Israel, but he declined it, though he did help found the Hebrew University of Jerusalem.

Misconceptions About Albert Einstein:

The rumor began circulating even while Albert Einstein was alive that he had failed mathematics courses as a child. While it is true that Einstein began to talk late - at about age 4 according to his own accounts - he never failed in mathematics, nor did he do poorly in school in general. He did fairly well in his mathematics courses throughout his education and briefly considered becoming a mathematician. He recognized early on that his gift was not in pure mathematics, a fact he lamented throughout his career as he sought out more accomplished mathematicians to assist in the formal descriptions of his theories.

DIET ACCORDING TO YOUR BLOOD TYPE:

In the modern world, there are a lot of people who want to lose weight, and they do their best to follow the diet. Anyway, finding out the right natural way to lose weight and get the results immediately is difficult.

Nonetheless, the human’s blood type is an important factor for the manifestation of the personality as well as health. So, as a reason to this, Dr. Peter J. D’Adamo got an idea of a special diet according to the blood types.

1. BLOOD TYPE A

People with this blood type have structures, peaceful, and balanced life surrounded by a supportive community. And, according to Dr. D’Adamo, these people may lose a lot of weight if they do not consume meat and veggies.

Furthermore, the doctor recommends that these people should consume organic, fresh, and clean types of diets. Many people who have this type of blood possess a sensitive immune system, so, they may discharge it, which will cause many illnesses.

Recommended foods are beans, fruits, and veggies, legumes, organic and fresh whole grains.

2. BLOOD TYPE B

People with this type of blood have the genetic potential for increased malleability and are capable of adapting to changeable environments. These people should not consume foods that have an impact on their metabolisms such as lentils, corn, sesame seeds, wheat, peanuts, tomatoes, chicken, and buckwheat.

But, are recommended to eat veggies, eggs, meats, and low-fat dairy.

3. BLOOD TYPE AB

Usually, people with this diet have a balance between life challenge making decisions. They are lovable people and are fortunate in love. Even though Dr. D’Adamo believes that these people have low stomach acid, they love meat.

So, when they consume meat, their stomach does not metabolize the meat, and it stores fats. But, eating small amounts of meat may fix this problem. They should eat dairy, seafood, green veggies, and tofu, and to avoid alcohol, caffeine, as well as smoked and cured meats.

4. BLOOD TYPE O

These people can easily digest many kinds of meals that contain high amounts of protein and fat. And, according to Dr. Adamo, that is a result of having high stomach acids. So, the doctor recommends to these people to eat meat, fish, poultry, and veggies as much as they want, but avoid carbs, especially grains.

CONDITIONS

If a person suffers from a chronic condition, for instance, diabetes, they may be recommended to consume high protein. On the other hand, there may be people with diabetes that would be recommended to avoid chicken or dairy. This may interfere with the treatment of diabetes.

According to the American Diabetes Association, you should not exclude any major food groups. Even though weight loss may have a positive effect on your overall health, you should always follow the AHA (American Heart Association) guideline for consuming low fat and low salt foods.

Also, people need to have 150 minutes of physical exercise per week.

After all, you need to consult your doctor before you decide which diet you would use in order to lose weight.

FUN TEST:

Everyone loves a good psychological test now and then as it makes good reading and a chance to dig deep into your personality. While there are many online, some are truly unique in the manner of testing such as these, where the image you see first reveals your personality.

Given below are two in one image entwined with one another designed in such a way that your mind registers only one image at first glance. Don’t prolong too long over an image. Only regard what you see first as that image is the one that will give you the correct analysis of your personality. The test is based on 3 kinds of optical illusions such as literal illusions that can create images different from the actual ones that make them. Cognitive illusions resulting from unconscious reasoning and psychological illusions that result from excessive stimulation. So go ahead and take the test.

Take a good look at the above image. What did you see?

If you saw a car, that probably means that your freedom is important to you.

The ability to hit the road, meet new people, see new places, and experience new things is near and dear to your heart. You usually take life at your own pace and do what comes naturally.

If you saw a man with binoculars, it indicates that you tend to be more analytical.

You look at the bigger picture and disregard minor details for the most part. You’re usually able to learn visually and absorb information quickly. You might want to make sure you pay attention to detail more consciously.

If you saw the letter A, which is arguably the most difficult thing to see first in the image, it means you have an eagle eye unmatched by most.

You tend to see the little details and are a little more intuitive than people who saw a man with binoculars or a car.

Basic Facts About Clouds:

Clouds may look like big, fluffy marshmallows in the sky, but in reality, they are visible collections of tiny water droplets (or ice crystals, if it's cold enough) that live high in the atmosphere above the Earth's surface. Here, we discuss the science of clouds: how they form, move, and change color.

Formation

Clouds form when a parcel of air rises from the surface up into the atmosphere. As the parcel ascends, it passes through lower and lower pressure levels (pressure decreases with height).

Recall that air tends to move from higher to lower pressure areas, so as the parcel travels into lower pressure areas, the air inside of it pushes outward, causing it to expand. This expansion uses heat energy and therefore cools the air parcel. The farther upward it travels, the more it cools. When its temperature cools to that of its dew point temperature, the water vapor inside of the parcel condenses into droplets of liquid water. These droplets then collect on the surfaces of dust, pollen, smoke, dirt, and sea salt particles called nuclei. (These nuclei are hygroscopic, meaning they attract water molecules.) It is at this point—when water vapor condenses and settles onto condensation nuclei—that clouds form and become visible.

Shape

Have you ever watched a cloud long enough to see it expanding outward, or looked away for a moment only to find that when you look back its shape has changed?

If so, you'll be glad to know it isn't your imagination. The shapes of clouds are ever-changing thanks to the processes of condensation and evaporation.

After cloud forms, condensation doesn't stop. This is why we sometimes notice clouds expanding into the neighboring sky. But as currents of warm, moist air continue to rise and feed condensation, drier air from the surrounding environment eventually infiltrates the buoyant column of air in a process called entrainment.

When this drier air is introduced into the cloud body, it evaporates the cloud's droplets and causes parts of the cloud to dissipate.

Movement 

Clouds start out high up in the atmosphere because that's where they're created, but they remain suspended thanks to the tiny particles they contain.

A cloud's water droplets or ice crystals are very small, less than a micron (that's less than one-millionth of a meter). Because of this, they respond very slowly to gravity. To help visualize this concept, consider a rock and a feather. Gravity affects each, however, the rock falls quickly whereas the feather gradually drifts to the ground because of its lighter weight. Now compare a feather and an individual cloud droplet particle; the particle will take even longer than the feather to fall, and because of the particle's tiny size, the slightest movement of air will keep it aloft. Because this applies to each cloud droplet, it applies to the entire cloud itself.

Clouds travel with the upper-level winds. They move at the same speed and in the same direction as the prevailing wind at the cloud's level (low, middle, or high).

High-level clouds are among the fastest moving because they form near the top of the troposphere and are pushed by the jet stream.

Color

A cloud's color is determined by the light it receives from the Sun. (Recall that the Sun emits white light; that white light is made up of all the colors in the visible spectrum: red, orange, yellow, green, blue, indigo, violet; and that each color in the visible spectrum represents an electromagnetic wave of a different length.)

The process works like this: As the Sun's lightwaves pass through the atmosphere and clouds, they meet the individual water droplets that make up a cloud. Because the water droplets have a similar size as the wavelength of sunlight, the droplets scatter the Sun's light in a type of scattering known as Mie scattering in which all wavelengths of light are scattered. Because all wavelengths are scattered, and together all colors in the spectrum make up white light, we see white clouds.

In the case of thicker clouds, such as stratus, sunlight passes through but is blocked. This gives the cloud a grayish appearance.

The History of Facebook and How It Was Invented:

Mark Zuckerberg was a Harvard computer science student when he, along with classmates Eduardo Saverin, Dustin Moskovitz, and Chris Hughes invented Facebook. However, the idea for the website, the world's most popular social networking page, oddly enough, was inspired by a botched effort to get internet users to rate each other's photos. 

Hot or Not?: The Origin of Facebook

In 2003, Zuckerberg, a second-year student at Harvard at the time, wrote the software for a website called Facemash.

He put his computer science skills to good use by hacking into Harvard's security network, where he copied the student ID images used by the dormitories and used them to populate his new website. Interestingly enough, he had initially created the site as a type of "hot or not" game for fellow students. Website visitors could use the site to compare two student photos side-by-side and decide who was "hot" and who was "not." 

Facemash opened on October 28, 2003, and closed a few days later, after it was shut down by Harvard execs. In the aftermath, Zuckerberg faced serious charges of breach of security, violating copyrights and violating individual privacy for stealing the student photos he used to populate the site. He also faced expulsion from Harvard University for his actions. However, all charges were eventually dropped.

TheFacebook: An App for Harvard Students

On February 4, 2004, Zuckerberg launched a new website called "TheFacebook." He named the site after the directories that were handed out to university students to aid them in getting to know one another better.

Six days later, he again got into trouble when Harvard seniors Cameron Winklevoss, Tyler Winklevoss and Divya Narendra accused him of stealing their ideas for an intended social network website called HarvardConnection and of using their ideas for TheFacebook. The claimants later filed a lawsuit against Zuckerberg, but the matter was eventually settled out of court.

Membership to the website was at first restricted to Harvard students. Over time, Zuckerberg enlisted a few of his fellow students to help grow the website. Eduardo Saverin, for example, worked on the business end while Dustin Moskovitz was brought on as a programmer. Andrew McCollum served as the site's graphic artist and Chris Hughes became the de facto spokesperson. Together the team expanded the site to additional universities and colleges.

Facebook: The World's Most Popular Social Network

In 2004, Napster founder and angel investor Sean Parker became the company's president. The company changed the site's name from TheFacebook to just Facebook after purchasing the domain name facebook.com in 2005 for $200,000.

The following year, venture capital firm Accel Partners invested $12.7 million in the company, which enabled the creation of a version of the network for high school students. Facebook would later expand to other networks such as employees of companies. In September of 2006, Facebook announced that anyone who was at least 13 years old and had a valid email address could join. By 2009, it had become the world's most used social networking service, according to a report by the analytics site Compete.com.

While Zuckerberg's antics and the site's profits eventually led to him becoming the world's youngest multi-billionaire, he's done his part to spread the wealth around. He's donated $100 million dollars to the Newark, New Jersey public school system, which has long been underfunded. In 2010, he signed a pledge, along with other wealthy businessmen, to donate at least half of his wealth to charity. Zuckerberg and his wife, Priscilla Chan, have donated $25 million toward fighting the Ebola virus and announced that they would contribute 99% of their Facebook shares to the Chan Zuckerberg Initiative to improve lives through education, health, scientific research, and energy.  

Geography and Overview of Yellowstone National Park:

Yellowstone is the United States' first national park. It was established on March 1, 1872, by President Ulysses S. Grant. Yellowstone is mainly located in the state of Wyoming, but it also extends into Montana and a small part of Idaho. It covers an area of 3,472 square miles (8,987 sq km) that is made up of various geothermal features like geysers, as well as mountains, lakes, canyons, and rivers.

The Yellowstone area also features many different types of plants and animals. 

History of Yellowstone National Park

The history of humans in Yellowstone dates back to around 11,000 years ago when Native Americans began to hunt and fish in the region. It is believed that these early humans were a part of the Clovis culture and used the obsidian in the region to make their hunting weapons, mainly Clovis tips, and other tools. 

Some of the first explorers to enter the Yellowstone regions were Lewis and Clark in 1805. During their time spent in the area, they encountered several Native American tribes such as the Nez Perce, Crow, and Shoshone. In 1806, John Colter, who was a member of the Lewis and Clark expedition, left the group to join fur trappers - at which point he came across one of the park's geothermal areas. 

In 1859 some early explorations of Yellowstone took place when Captain William Reynolds, a U.S. Army surveyor, began exploring the northern Rocky Mountains.

Exploration of the Yellowstone area was then interrupted due to the beginning of the Civil War and did not officially resume until the 1860s.

One of the first detailed, explorations of Yellowstone occurred in 1869 with the Cook-Folsom-Peterson Expedition. Shortly thereafter in 1870, the Washburn-Langford-Doane Expedition spent a month surveying the area, collecting different plants and animals and naming unique sites.

Following that expedition, Cornelius Hedges, a writer, and lawyer from Montana who had been a part of the Washburn expedition suggested making the region a national park. 

Although there was much action to protect Yellowstone in the early 1870s, serious attempts to make Yellowstone a national park did not occur until 1871 when geologist Ferdinand Hayden completed the Hayden Geological Survey of 1871. In that survey, Hayden gathered a complete report on Yellowstone. It was this report that finally convinced the United States Congress to make the region a national park before it was bought by a private landowner and taken away from the public. On March 1, 1872, President Ulysses S. Grant signed the Act of Dedication and officially created Yellowstone National Park. 

Since its founding, millions of tourists have visited Yellowstone. In addition, roads, several hotels like the Old Faithful Inn and visitor centers, such as the Heritage and Research Center, have been constructed within the park's boundaries. Recreational activities like snowshoeing, mountaineering, fishing, hiking, and camping are also popular tourist activities in Yellowstone.

Yellowstone's Geography and Climate

96% of Yellowstone's land is within the state of Wyoming, while 3% is in Montana and 1% is in Idaho.

Rivers and lakes make up 5% of the park's land area and the largest body of water in Yellowstone is Yellowstone Lake, which covers 87,040 acres and is up to 400 feet (120 m) deep. Yellowstone Lake has an elevation of 7,733 feet (2,357 m) which makes it the highest altitude lake in North America. The remainder of the park is mostly covered by forest and a small percentage of grassland. Mountains and deep canyons also dominate much of Yellowstone.

Because Yellowstone has variations in altitude, this determines the park's climate. Lower elevations are milder, but in general summers in Yellowstone average 70-80°F (21-27°C) with afternoon thunderstorms. Yellowstone's winters are normally very cold with highs of just 0-20°F (-20- -5°C). Winter snow is common throughout the park.

Geology of Yellowstone

Yellowstone was initially made famous due to its unique geology caused by its location on the North American plate, which for millions of years has slowly moved across a mantle hotspot via plate tectonics.

The Yellowstone Caldera is a volcanic system, the largest in North America, which has formed as a result of this hot spot and subsequent large volcanic eruptions.

Geysers and hot springs are also common geologic features in Yellowstone which have formed due to the hotspot and geologic instability. Old Faithful is Yellowstone's most famous geyser but there are 300 more geysers within the park.

In addition to these geysers, Yellowstone commonly experiences small earthquakes, most of which are not felt by people. However, large earthquakes of magnitudes 6.0 and greater have struck the park. For example in 1959 a magnitude 7.5 earthquake hit just outside the park's boundaries and caused geyser eruptions, landslides, extensive property damage and killed 28 people.

Yellowstone's Flora and Fauna

In addition to its unique geography and geology, Yellowstone is also home to many different species of plants and animals. For example, there are 1,700 species of trees and plants native to the Yellowstone area. It is also home to many different species of fauna- many of which are considered megafaunas such as grizzly bears and bison. There are around 60 animal species in Yellowstone, some of which include the gray wolf, black bears, elk, moose, deer, bighorn sheep and mountain lions. Eighteen species of fish and 311 species of birds also live within Yellowstone's boundaries.

The Best Sites to Learn a New Word Every Day:

In terms of vocabulary development, we were all little geniuses in childhood, learning hundreds of new words every year. By the time we entered first grade, most of us had active vocabularies of several thousand words.

Unfortunately, we weren't geniuses for very long. By age 11 or 12, equipped with a sizable survival vocabulary, most of us lost some of our early enthusiasm for language, and the rate at which we picked up new words began to decline significantly.

As adults, if we don't make deliberate efforts to increase our vocabularies, we're lucky to pick up even 50 or 60 new words a year.

The English language has so much to offer (at least half a million words by most reckonings) that it would be a shame to let our vocabulary-building talents go to waste. So here's one way that we can regain some of our youthful brilliance: learn a new word each day.

Whether you're a student preparing for the SAT, ACT, or GRE, or simply an unabashed logophile (or lover of words), starting each day with a fresh word can be intellectually nourishing—and more enjoyable than a bowl of All-Bran.

Here are three of our favorite daily word sites: all are free and available through e-mail subscriptions.

1) A.Word.A.Day (AWAD)

Founded in 1994, A.Word.A.Day at Wordsmith.org is the creation of Anu Garg, an India-born computer engineer who clearly enjoys sharing his pleasure in words.

Simply designed, this popular site (over a million subscribers from more than 170 countries) offers concise definitions and examples of words that relate to a different theme every week. The New York Times has called this "the most welcomed, most enduring piece of daily mass e-mail in cyberspace." Recommended for all word lovers.

2) Oxford English Dictionary Word of the Day

For many of us, the Oxford English Dictionary is the ultimate reference work, and the OED Word of the Day provides a complete entry (including a wealth of illustrative sentences) from the 20-volume dictionary. You can sign up to have the OED's Word of the Day delivered by e-mail or RSS web feed. Recommended for scholars, English majors, and logophiles.

Recommended for high school and college students as well as advanced ESL students.

Solving Everyday Problems With Science:

Chemistry offers simple solutions to life's everyday little problems. Here are some easy tips to help get you through the day.

Test Eggs in Water

Here's a life hack to keep you from cracking open a bad raw egg. Place the egg in a cup of water. If it sinks, it's fresh. If it floats, you can use it for a stinky prank, but you won't want to eat it. A decaying egg produces hydrogen sulfide. This is the chemical responsible for the foul rotten egg stench. The gas also makes the bad egg buoyant in water.

Use Chemistry To Polish Silver

Silver reacts with air to form a black oxide termed tarnish. If you use or wear silver, this layer gets worn away so the metal stays fairly bright. However, if you keep your silver for special occasions, it can blacken. Polishing silver by hand may be good exercise, but it's not fun. You can use chemistry to prevent most of the tarnish from forming and to remove it without polishing.

Prevent tarnish by wrapping your silver before you store it. Plastic wrap or a plastic bag prevents air from circulating around the metal. Squeeze out as much air as possible before tucking the silver away. Keep silver away from humidity and products high in sulfur.

To remove tarnish electrochemically from fine silver or sterling silver, line a dish with aluminum foil set the silver on the foil, pour on hot water and sprinkle the silver with salt and baking soda. Wait 15 minutes, then rinse the silver with water, dry it, and marvel at the shine.

Make Better Ice Cubes

Use chemistry to make better ice! If your ice cubes aren't clear, try boiling the water and then freezing it. Boiling water drives off dissolved gases that can make ice cubes appear cloudy.

Another tip is to make ice cubes from the liquid you are drinking. Don't dilute lemonade or iced coffee with frozen water. Drop frozen lemonade or frozen coffee cubes into the drinks. Although you can't freeze hard alcohol, you can make ice cubes using wine.

Threading the Needle

There are tools that can make it easier to thread a needle, but if you don't have one, you can make the process easier by binding together the fibers of the thread. Lightly run the thread through a bit of candle wax or paint the end with nail polish. This binds the stray fibers and stiffens the thread so it won't bend away from the needle. If you have trouble seeing the thread, bright polish can make it easier to spot the end. Of course, the easiest solution to this problem is to find a youthful helper to thread the needle for you.

Ripen Bananas Quickly

You found the perfect bunch of bananas, except for one little problem. They are still green. You can wait around a couple of days for the fruit to ripen on its own or you can speed up the process using chemistry. Simply close your bananas in a paper bag, along with an apple or ripe tomato. The apple or tomato gives off ethylene, which is a natural fruit ripening chemical. On the flip side, if you want to keep your bananas from getting overly ripe, don't put them in the fruit bowl with other ripe fruit.

Add Salt To Make Coffee Taste Better

Did you order a cup of coffee, only to find it tastes like battery acid? Reach for the salt shaker and sprinkle a few grains into your cup of joe. Salt dissolves in coffee to release sodium ions. The coffee won't be any better, but it will taste better because the sodium blocks taste receptors from detecting the bitter notes.

If you are brewing your own coffee, you can add salt during the brewing process. Another tip to reduce bitterness is to avoid brewing coffee with super-hot water or letting it sit on a hot plate until the end of time. Too much heat during brewing increases extraction of the molecules that taste bitter while holding coffee on a hot plate eventually burns it.
