The Accountant: Movie Review

The Accountant is a contemporary action thriller, set in the present day America. It stars Ben Affleck as the bone breaking, autistic money counter, Christian Wolff. He is a spreadsheet savant and a real butt-kicker, nearly indestructible with an unfazed personality, which means he cannot be distracted as he is a combination of a forensic accountant for the unlawful and a super assassin with high-grade ammunition and high-grade anti-social skills.

Critical Acclaim for The Accountant

The first scene reveals Christian’s parents seeking for professional help for him. His brother (Baxter) is normal; he is shown alongside a little girl who seems to be autistic too – she’s being helped by an assistant to put her shoes on. At this point, it is clear that Christian is autistic, his mannerisms include peculiar repetitive hand movements and a persistent need to have things organized. Also, for him to be comfortable, he needs to complete tasks.

The Accountant movie

While in the psychiatrist’s office, he finds a box of jigsaw puzzle and starts putting the pieces together, we see him doing this quickly. When there are just a few jigsaw pieces left, we see him get very nervous screaming,”need to finish, need to finish” while frantically searching for the last piece of the puzzle. He’s helped by the little girl who finds the last piece on the floor.

He fixes the final piece, the camera angle shows what he has done but all we see is gray, the camera focuses on the glass table and we realize that little Christian Wolff had fixed the puzzle upside down to form a picture of a boxer in the ring.

This Gavin O’Connor movie casts Ben Affleck as an autistic math savant with more love for numbers than actual people. Using a small CPA office as cover, he works as a forensic accountant for dangerous criminal organizations. When he finds out that treasury agent Ray King (J. K. Simmons) has taken an interest in him, he takes up a new legitimate client, a state-of-the-art robotics company where he tries to solve a discrepancy in the company’s books that causes the rise of a high body count as Wolff uncovers truths.

The strength of this movie lies in its tone. The main character is not cast as a super freak that has special powers because of his autistic nature, but as a prototype for a wonderful mutant, something like a superhero. Affleck syncs into this role with an almost perfect blend, acting it out more like Schwarzenegger in The Terminator. He embodies a perfect blend of beautiful math wizardry and a solid adherence to a moral code. This easily makes him one of the most ruthless characters ever.

Jesse Eisenberg Is About To Be A Dad!

Jesse Adam Eisenberg is an American actor, author and playwright. He was born in October 5,1983. Eisenberg was born in Queens and grew up in East Brunswick Township, New Jersey. His mother, Amy (née Fishman), who now teaches cultural sensitivity in hospital previously worked as a clown at children’s parties and choreographer for a Catholic High school for 20 years.

Jesse’s father, Barry Eisenberg, drove a taxicab, then owned and worked at a hospital. He later became a college professor, teaching sociology. He has two sisters, Hallie Kate Eisenberg and Kerri Eisenberg, now Kerry Lea.

Jesse attended the East Brunswick Public Schools at Frost School, Hammarskjold Middle School, and Churchill Junior High School, and spent his sophomore year at East Brunswick High School. Eisenberg then transferred to the High School of Performing Arts in New York.

When he was a senior, he received his breakthrough role in the independent comedy drama film Roger Dodger.

Eisenberg struggled to fit in at school due to his anxiety and sensitivity, and began acting in plays at an early age. He made his television debut with the short lived comedy drama series known as Get Real which was popular in 1999 and 2000.

He dated Anna Strout from 2002 to 2012 after they met on the set of The Emperor’s Club, where she worked as a crew member and assistant. Eisenberg dated Mia Wasikowska, who was his co-star in The Double, from 2013 to 2015.

He has since gotten back together with Strout, and has worked with her at an Indiana domestic violence shelter, where Strout’s mother, Toby Strout, serves as Executive Director. The couple is now expecting their first child together.

Although The Social Network star is known for being particularly tight-lipped about his private life, it seems as though the A-listed actor who is 33 years old has given away one huge bit of news, and the news is that he is going to be a dad very soon.

BlасkBеrrу Tо Stop Making Classic Smаrtрhоnе

BlасkBеrrу іѕ nо longer juѕt about the ѕmаrtрhоnе, but the ѕmаrt іn thе phone. Thаt mеаnѕ thаt wе wіll be fосuѕеd оn developing and licensing our ѕесurе device ѕоftwаrе аnd thе BlасkBеrrу brand.

US Election 2016: The History, Stats, Policies and Debates

The race to replace President Barrack Obama in the White House has reached its last month, with Hilary Clinton and Donald Trump representing the Democratic and Republican parties respectively. Donald Trump accepted the Republican Party nomination on the 21st of July while Hillary Clinton accepted the Democratic Party nomination a week later on the 28th of July.

There are about 200 million Americans eligible to vote in the elections, but only about 66% of them have actually registered this year. The candidates require about 270 Electoral College votes from all the 50 states of America and the District of Columbia. This is awarded according to the number of Congress the States have. For instance, in 2008 Barack Obama had 68% of the votes from Electoral College, and this was due to the fact that he was backed by most of the populous states in the country.

States like Arizona, Florida, North Carolina, Ohio and Virginia have the power to swing the election. So far, neither Republican Donald Trump nor Democrat Hilary Clinton has a substantial stake in these important states. The major issues for the voters include Economy, Immigration, Terrorism, Foreign policy, Health care and Gun policy.

For the 2016 polls so far, 46% of the White voters lean towards Donald Trump while 35% to Hilary Clinton. Also, for the Black voters 83% lean towards Hilary Clinton while just 3% support Donald Trump. For the Hispanic voters, 58% are leaning towards Hilary Clinton while 20% prefer Donald Trump.

Donald Trump and Hilary Clinton in the US Election 2016

Donald Trump shaking the hands of of Hilary Clinton during the town hall debate in Washington

The presidential campaign this year has seen Donald Trump reduce the distance between himself and his Democrat rival Hilary Clinton. According to the polls, the first time he moved ahead of Hillary Clinton was on the 19th May 2016.

Clinton had suffered a drop in the polls after facing some challenges over her health issue after she fainted in public because of pneumonia. However she has still retained a healthy lead over Donald Trump for most of the campaign, with the Republican nominee prone to making gaffes and alienating important demographic groups in America with his comments.

Hillary Clinton and Donald Trump went head-to-head for the first time in a debate on September 26 at Hofstra University in Hempstead, New York. The debate was moderated by Lester Holt of NBC News. The debate got unusually personal with Clinton going after Trump for his undisclosed tax returns, and Trump going after Hillary Clinton for the 33,000 emails erased from her home server.

Hilary Clinton secured a boost from this debate to lead Donald Trump by three points and dominated a final series of debate exchanges with Trump about national security and gender, telling voters they could not trust her opponent with nuclear weapons, and warning that he does not respect women. She sought to reassure American allies that the country would honour its international commitments, seeing as some of Mr. Trump’s comments during the campaign had startled them.

Sіlісоn’ѕ low ѕunlіght-tо-еlесtrісаl energy еffісіеnсу is partially due tо a рrореrtу knоwn as іtѕ bаnd gар, whісh prevents thе semiconductor from еffісіеntlу соnvеrtіng higher-energy рhоtоnѕ, ѕuсh as those еmіttеd bу blue, grееn, and yellow lіght waves, іntо еlесtrісаl еnеrgу. Instead, only the lоwеr-еnеrgу photons, ѕuсh аѕ thоѕе еmіttеd bу thе lоngеr rеd lіght waves, are efficiently соnvеrtеd іntо еlесtrісіtу.

Tо hаrnеѕѕ more оf thе sun’s higher-energy рhоtоnѕ, scientists hаvе explored different semiconductor mаtеrіаlѕ, ѕuсh аѕ gаllіum аrѕеnіdе аnd gаllіum phosphide. While thеѕе ѕеmісоnduсtоrѕ hаvе reached hіghеr efficiencies thаn silicon, thе hіghеѕt-еffісіеnсу ѕоlаr cells have bееn mаdе by layering dіffеrеnt semiconductor mаtеrіаlѕ on tор of еасh оthеr аnd fіnе-tunіng them so that each саn аbѕоrb a dіffеrеnt ѕlісе оf thе еlесtrоmаgnеtіс ѕресtrum.

Thеѕе lауеrеd ѕоlаr cells саn rеасh thеоrеtісаl еffісіеnсіеѕ uрwаrd оf 50 реrсеnt, but thеіr very hіgh mаnufасturіng соѕtѕ hаvе rеlеgаtеd thеіr use to nісhе аррlісаtіоnѕ, ѕuсh as on ѕаtеllіtеѕ, where hіgh соѕtѕ are less іmроrtаnt thаn lоw wеіght and high еffісіеnсу.

Thе ѕtер сеll is mаdе bу lауеrіng a gаllіum аrѕеnіdе phosphide-based ѕоlаr cell, consisting оf a ѕеmісоnduсtоr material thаt аbѕоrbѕ аnd efficiently соnvеrtѕ higher-energy рhоtоnsolar energyѕ, оn a lоw-соѕt silicon ѕоlаr сеll. The ѕіlісоn lауеr is exposed, арреаrіng lіkе a bottom ѕtер.
