Over the years we've seen many actors portray God on the big screen, from George Burns to Morgan Freeman, but now it is apparently Octavia Spencer's time toe become omnipotent and all-powerful. This is because she is now in final negotiations to play God in an adaptation of the novel The Shack, which is now in the works over at Lionsgate.

The major role for the student is to well-study, work smarter not harder is a very common phrase which every student have to listen and also tried to follow that too. Every student has crowded schedule to complete their works, college, assignments, projects, social events and some other activates such make them too tired for study at home. For the smarter study, you need a perfect schedule including your all activities of the day which you have to follow strictly to cover up your studies. Instead of studying longer and harder, scientific research has proven ways on how the brain can process and learn information smarter and within shorter time spans. To study smarter UK Dissertation Help provider suggest some assure tips which help you
Concentrate on studies
Before the one or two months of exams students decide to study hard with the proper schedule, and that time they need more concentration towards their studies. Prepare a complete schedule and to-do list for a day and also to solve the previous year question paper which will help you to understand the pattern and also the efforts you have to give for that subject.
Create milestones
During exam time there is a lot of pressure and we have to manage all the things in the same time. Before starting any topic or subject just divide it into different parts which will help you complete your target and also have your own progress report that how much time taken to complete one task. Take a break of 5 min after every 30 min which will help you to get a refresh. Discipline yourself to study your toughest subject for 20-30 minutes a day or to solve 5-10 problems of your textbook every single day. A small daily effort piles up – after 30 days, just 5 problems a day pile up to 150 problems solved.
Smart study, instead of hard
Always study according to the timetable and when you study just completely concentrate on your subject avoiding all the destruction, keeping them and study for the whole day will never give you a positive result. Make sure before leaving the topic each and every concept should be clear, make proper and understanding notes with highlighting important points which help you during revision.
Keep track of your progress
Check you’re to do list daily before sleeping and make sure that have you completed your task of the day and it helps also to manage the time that which subject need more time to complete. Stay focus till your exams end it will help you to score more result.
Never give up
Practice, practice, practice until you don’t achieve your goal, never try to give up and remained focused on your goal. Never distract from any other thing until you achieve your goal.

It would literally be decades before we found out this was a part of African American History, as the book and movie "Hidden Figures" reveals. We have been, and always will be a part of the fabric of this nation's progress forward. Regarding us as lazy, stupid, useless can only lead to the United States regression into third world status. It has the logic of shooting oneself in the foot and expecting "the other" to feel the pain.
I guess for my mother, it was t-minus six months and counting (I was happily gestating in her womb)...
It took chutzpah, moxie for a human being to consciously strap (at that time) himself to a large lit stick of dynamite with no guarantee that the procedure, though thoroughly calculated and considered, would not end in disaster.
So was this Marine Corp pilot, who confidently climbed into a Mercury rocket - Friendship 7, and took the first flight by an American to orbit the Earth.
Mercury - Gemini - Apollo: it would change our world with semiconductor-manufactured spinoff technologies that we now take for granted. It would change our focus, our nerve on what was possible. We would look to the stars and listen for signs of humanity's cousins.

Helium doesn’t play well with others. Beyond its noble gas designation on the periodic table, it has the lowest electron affinity—zero—among the elements, and the highest ionization energy. Scientists have managed to mechanically pack He atoms with other elements, but the He has little effect on those compounds’ characteristics.
Now an international team has presented evidence for a compound whose electronic structure and thus its physical properties are influenced by its He components. Researchers led by Artem Oganov ran a crystal structure prediction algorithm to play matchmaker for He and found that the compound Na2He should form at high pressures. The researchers shared their prediction with Alexander Goncharov and colleagues, who loaded He gas and solid sodium into a diamond-anvil cell at the Carnegie Institution for Science. After increasing the pressure to 140 GPa and heating the sample, Goncharov’s team noticed a marked shift in material properties. New peaks appeared in x-ray diffraction patterns, and the sample’s melting point rose to more than 1500 K; pure Na melts at about 550 K.

Recently, scientists made some impressive measurements of light emitted by an isolated neutron star. The results support an 80-year-old prediction, made during the early days of quantum electrodynamics (QED), of a phenomenon known as vacuum birefringence.
Radio signals, microwaves, visible light, ultraviolet, X-rays, and gamma rays are all types of electromagnetic waves. All electromagnetic waves travel through empty space at the same speed, the speed of light (~300,000,000 m/s). More energetic electromagnetic waves have higher frequencies and shorter wavelengths.
In the diagram
When scientists say that light is polarized, they are referring to the direction of the electric field, depicted in the above diagram by the blue arrows. In the diagram, the electromagnetic wave is polarized in the z direction. That is to say: all of the electric field vectors are aligned (whether up or down) with the z axis.
When scientists make measurements on electromagnetic waves, they measure many waves. Most light is randomly polarized, so if you try to collect some light headed in the x direction, you’ll find just as many electromagnetic waves on the z axis as on the y axis, and at all angles in between. This type of light would be called unpolarized.
Most typical low- and medium-mass stars (anywhere from 0.1 to 3 times the mass of our Sun) use up their fuel in nuclear fusion then quietly cool off, usually forming a white dwarf. More massive stars have a lot more gravitational pull, so they burn up their fuel faster, resulting in a shorter life span and an explosive finale called a supernova. A supernova spews much of the material of the star outward, but what is left (which again depends on the initial mass of the star) becomes either a neutron star (if the initial mass was between 8 and 24 times the mass of our Sun) or a black hole (initial mass 25 or more times the mass of our Sun).
Although neutrons are neutrally charged, they are composed of charged particles that cause the neutron to have a magnetic dipole—that is, neutrons act like little magnets. Collectively, the number of neutrons that make up a 12- to 20-mile-diameter ball put out an incredible magnetic field. As a neutron star rotates, its rotating magnetic field creates radio waves that are emitted like beacons from the magnetic poles of the star. To our observatories, these signals appear to pulsate. As a result, neutron stars are sometimes called pulsars. Neutron stars don’t emit very much visible light, but they emit some.

Replica of Benjamin Banneker's clock at Brookhaven National Laboratory link below |
Topics: African Americans, History, Diaspora, Diversity in Science, Women in Science
Without Benjamin Banneker, our nation's capital would not exist as we know it. After a year of work, the Frenchman hired by George Washington to design the capital, L'Enfant, stormed off the job, taking all the plans. Banneker, placed on the planning committee at Thomas Jefferson's request, saved the project by reproducing from memory, in two days, a complete layout of the streets, parks, and major buildings. Thus Washington, D.C. itself can be considered a monument to the genius of this great man.
Banneker's English grandmother immigrated to the Baltimore area and married one of her slaves, named Bannaky. Later, their daughter did likewise, and gave birth to Benjamin in 1731. Since by law, free/slave status depended on the mother, Banneker, like his mother, was---technically---free.
Banneker attended an elementary school run by Quakers (one of the few "color-blind" communities of that time); in fact, he later adopted many Quaker habits and ideas. As a young man, he was given a pocket-watch by a business associate: this inspired Banneker to create his own clock, made entirely of wood (1753). Famous as the first clock built in the New World, it kept perfect time for forty years.
During the Revolutionary War, wheat grown on a farm designed by Banneker helped save the fledgling U.S. troops from Banneker's clock starving. After the War, Banneker took up astronomy: in 1789, he successfully predicted an eclipse. From 1792 to 1802, Banneker published an annual Farmer's Almanac, for which he did all the calculations himself.
The Almanac won Banneker fame as far away as England and France. He used his reputation to promote social change: namely, to eliminate racism and war. He sent a copy of his first Almanac to Thomas Jefferson, with a letter protesting that the man who declared that "all men are created equal" owned slaves. Jefferson responded with enthusiastic words, but no political reform. Similarly, Banneker's attempts "to inspire a veneration for human life and an horror for war" fell mainly on deaf ears.
But Banneker's reputation was never in doubt. He spent his last years as an internationally known polymath: farmer, engineer, surveyor, city planner, astronomer, mathematician, inventor, author, and social critic. He died on October 25, 1806. Today, Banneker does not have the reputation he should, although the entire world could still learn from his words: "Ah, why will men forget that they are brethren?"
Banneker's life is inspirational. Despite the popular prejudices of his times, the man was quite unwilling to let his race or his age hinder in any way his thirst for intellectual development.
Benjamin Banneker, known as the first African-American man of science, was born in 1731 in Ellicott's Mills, Md. His maternal grandmother was a white Englishwoman who came to this country, bought two slaves and then liberated and married one of them; their daughter, who also married a slave, was Banneker's mother.
From the beginning, Banneker, who was taught reading and religion by his grandmother and who attended one of the first integrated schools, showed a great propensity for mathematics and an astounding mechanical ability. Later, when he was forced to leave school to work the family farm, he continued to be an avid reader.
Although he had no previous training, when he was only 22 he invented a wooden clock that kept accurate time throughout his life. According to "Gay & Lesbian Biography," Banneker "applied his natural mechanical and mathematical abilities to diagrams of wheels and gears, and converted these into three-dimensional wooden clock-parts he carved with a knife." People from all over came to see the clock.
