Viktor Schreckengost, the father of industrial design and creator of the Jazz Bowl, an iconic piece of Jazz Age art designed for Eleanor Roosevelt during his association with Cowan Pottery died yesterday. He was 101.

Schreckengost was born on June 26, 1906 in Sebring, Ohio, United States.

Schreckengost’s peers included the far more famous designers Raymond Loewy and Norman Bel Geddes.

In 2000, the Cleveland Museum of Art curated the first ever retrospective of Schreckengost’s work. Stunning in scope, the exhibition included sculpture, pottery, dinnerware, drawings, and paintings.

Vinay Deolalikar, a mathematician who works for HP Labs, claims to have proven that P is not equal to NP. The problem is the greatest unsolved problem in theoretical computer science and is one of seven problems in which the Clay Mathematics Institute has offered million dollar prizes to the solutions.

The question of whether P equals NP essentially asks whether there exist problems which take a long time to solve but whose solutions can be checked quickly. More formally, a problem is said to be in P if there is a program for a Turing machine, an ideal theoretical computer with unbounded amounts of memory, such that running instances of the problem through the program will always answer the question in polynomial time — time always bounded by some fixed polynomial power of the length of the input. A problem is said to be in NP, if the problem can be solved in polynomial time when instead of being run on a Turing machine, it is run on a non-deterministic Turing machine, which is like a Turing machine but is able to make copies of itself to try different approaches to the problem simultaneously.

Mathematicians have long believed that P does not equal NP, and the question has many practical implications. Much of modern cryptography, such as the RSA algorithm and the Diffie-Hellman algorithm, rests on certain problems, such as factoring integers, being in NP and not in P. If it turned out that P=NP, these methods would not work but many now difficult problems would likely be easy to solve. If P does not equal NP then many natural, practical problems such as the traveling salesman problem are intrinsically difficult.

In 2000, the Clay Foundation listed the “Clay Millenium Problems,” seven mathematical problems each of which they would offer a million dollars for a correct solution. One of these problems was whether P equaled NP. Another of theseseven, the Poincaré conjecture, was solved in 2002 by Grigori Perelman who first made headlines for solving the problem and then made them again months later for refusing to take the prize money.

On August 7, mathematician Greg Baker noted on his blog that he had seen a draft of a claimed proof by Deolalikar although among experts a draft had apparently been circulating for a few days. Deolalikar’s proof works by connecting certain ideas in computer science and finite model theory to ideas in statistical mechanics. The proof works by showing that if certain problems known to be in NP were also in P then those problems would have impossible statistical properties. Computer scientists and mathematicians have expressed a variety of opinions about Deolalikar’s proof, ranging from guarded optimism to near certainty that the proof is incorrect. Scott Aaronson of the Massachusetts Institute of Technology has expressed his pessimism by stating that he will give $200,000 of his own money to Deolalikar if the proof turns out to be valid. Others have raised specific technical issues with the proof but noted that the proof attempt presented interesting new techniques that might be relevant to computer science whether or not the proof turns out to be correct. Richard Lipton, a professor of computer science at Georgia Tech, has said that “the author certainly shows awareness of the relevant obstacles and command of literature supporting his arguments.” Lipton has listed four central objections to the proof, none of which are necessarily fatal but may require more work to address. On August 11, 2010, Lipton reported that consensus of the reviewers was best summarized by mathematician Terence Tao, who expressed the view that Deolalikar’s paper probably did not give a proof that P!=NP even after major changes, unless substantial new ideas are added.

A 21-year-old New Zealander, who has not been named, was sexually assaulted by another man early yesterday morning (NZDT) in Wellington, New Zealand. The New Zealand police have described the sexual attack as “prolonged and terrifying”.

The man was first threatened with a weapon at a shopping center located in Riddiford Street, Newtown, Wellington and was then forced into a dark and isolated carpark where the sexual attack occurred.

Detective Sergeant Zane Smith, said that they have been given a very good description of the attacker and with that description have released an identikit picture. The attacker is a male M?ori aged between mid-20s and early 30s, measures around 1.8 metres and has a solid build. The most identifiable feature is a M?ori tattoo located on his chin. The attacker was also wearing a ‘50 Cent‘ green hooded top, faded black baggy jeans and was wearing sneakers coloured red and white.

The attacker has still not been found and police are asking for anyone who may have been in the Riddiford Street shopping centre between 2:00 a.m. and 3:30 a.m.

CCTV (closed-circuit television) cameras are being examined.

A unanimously passed United Nations Security Council resolution imposing sanctions on Iran has been dismissed by Iranian president Mahmoud Ahmadinejad as a “piece of paper.” Ahmadinejad said that it is in “the best interest of the West” to have a “nuclear Iran” and that Iran will not stop enriching uranium.

“It is a piece of torn paper … by which they aim to scare Iranians … It is in the Westerners’ interests to live with a nuclear Iran,” said Ahmadinejad.

Ahmadinejad also goes on to say that anyone who “backs” the U.N. resolution will “soon regret” their acts. He also added that in “February, Iranians will celebrate” the nation becoming a nuclear power.

“This resolution will not harm Iran and those who backed it will soon regret their superficial act. Iranians are neither worried nor uncomfortable with the resolution … we will celebrate our atomic achievements in February,” added Ahmadinejad.

On December 23, 2006, the U.N. stated that the resolution is “determined to give effect to its unmet 31 July demand that Iran suspend all uranium enrichment-related and reprocessing activities. The Security Council today imposed sanctions on that country [Iran], blocking the import or export of sensitive nuclear material and equipment and freezing the financial assets of persons or entities supporting its proliferation sensitive nuclear activities or the development of nuclear-weapon delivery systems,” reported the press release on the U.N.’s website.

The U.N. also said that Iran must suspend all uranium enrichment and that the sanction would be lifted if the country complies with the U.N..

“Unanimously adopting resolution 1737 (2006) under Article 41 of the Charter’s Chapter VII, the Council decided that Iran should, without further delay, suspend the following proliferation sensitive nuclear activities: all enrichment-related and reprocessing activities, including research and development; and work on all heavy-water related projects, including the construction of a research reactor moderated by heavy water. The halt to those activities would be verified by the International Atomic Energy Agency (IAEA).”

The U.N. also stated that “specifically, all States [countries] should prevent the supply, sale or transfer, for the use by or benefit of Iran, of related equipment and technology, if the State determined that such items would contribute to enrichment-related, reprocessing or heavy-water related activities, or to the development of nuclear weapon delivery systems. The Council decided it would terminate the measures if Iran fully complied with its obligations, or adopt additional ones and possible further decisions if the country did not.”

Iran also said that beginning on “Sunday morning, we [Iran] will begin activities at Natanz” which has “3,000 centrifuges” which they “will drive them with full speed” in response to the U.N.’s resolution.

“From Sunday morning, we will begin activities at Natanz, the site of 3,000-centrifuge machines, and we will drive it with full speed. It will be our immediate response to the resolution,” said Ali Larijani, the top nuclear negotiator for Iran.

The U.N. will review the resolution and Iran’s activities in 60 days.

Cambridge, Massachusetts —Construction of two condominium buildings and a five-acre park began on March 21, in East Cambridge, Massachusetts. The buildings and park are part of the 45-acre Northpoint development, which will take 15 years and more than $2bn to complete, according to the Boston Globe. The buildings, designated as “Building S” and “Building T” by the planners of the project, Spaulding & Slye Colliers, have been designed by local architectural firm Childs Bertman Tseckares and Architects Alliance from Toronto. Buildings S and T are the first of an eventual 20 buildings planned at the site.

The development will fill what used to be a railroad yard for the Guilford Rail System, a subsidiary of Guilford Transportation Industries. According to Hoovers.com, Guilford is controlled by Timothy Mellon, heir to the Mellon banking fortune. Guilford Rail Systems has its headquarters in North Billerica and owns 1600 miles of railroad throughout New England. The tracks in the Northpoint plot have been removed, though Boston subway’s Lechmere station remains within walking distance of the site, along with parts of Boston and Cambridge. The site is bordered by Route 93 on its eastern side, Monsignor O’Brien Highway to the west, and the Gilmore Bridge to the south.

The landscape architecture of the park is provided by Michael Van Valkenburgh Associates, a landscape architecture firm on Concord Avenue in Cambridge. The firm’s principal teaches in Harvard’s Graduate School of Design. MVVA is also completing the landscape for Harvard’s Northwest Science Building.

B2B Trade Area of Taipei Game Show, criticized by trade buyers last year, but accompanied with 2008 Taiwan Digital Content Forum, moved to the second floor at Taipei World Trade Center for world-wide participants with a better exchange atmosphere this year.

Not only local OBMs (Softstar Entertainment, Soft-World International Corp., International Games System Corp., …, etc.) but also companies from New Zealand, Canada, Japan, Hong Kong, and South Korea showcased different specialists with multiple styles. Especially on South Korea, participated members from G? Trade Show (Game Show & Trade, All-Round, aka Gstar) showcased gaming industry of South Korea and the G? upcoming at this November with brochures.

In the 2-days Digital Content Forum, world-class experts not only shared industry experiences, members from Taiwan Gaming Industry Association also discussed and forecasted marketing models for gaming industry. With participations from governmental, industrial, and academical executives world-wide, this forum helps them gained precious experiences of digital content industry from several countries.

According to the Taipei Computer Association, the show and forum organizer, the digital content industry in Taiwan was apparently grown up recent years as Minister of Economic Affairs of the Republic of China Steve Ruey-long Chen said at Opening Ceremony yesterday. Without R&Ds from cyber-gaming, and basic conceptions from policies and copyright issues, this (digital content) industry will be fallen down in Taiwan. If this industry wanted to be grown up in sustainability, gaming OBMs in Taiwan should independently produce different and unique games and change market style to market brands and games to the world.
