Sorry, the Riemann Hypothesis Has Almost Certainly Not Been Solved

Sorry, the Riemann Hypothesis Has Almost Certainly Not Been Solved

Rumors are swirling that Opeyemi Enoch, a professor from the Federal University of Oye Ekiti in Nigeria, has solved the Riemann Hypothesis, a problem that has vexed mathematicians for over 150 years. Too bad it’s not true.

As reported in the BBC, The Telegraph, Yahoo! News, and many other publications, the Nigerian professor is claiming to have solved the problem, thus making him eligible for a $1 million dollar prize. Enoch has yet to make his solution public, so his claim has yet to be verified.

The problem, posited by mathematician Bernard Riemann in 1859, involves the average distribution of prime numbers (a straightforward, relatively non-mathy explanation can be found here). It’s one of seven Millennium Problems in Mathematics, a contest run by the Clay Mathematics Institute (CMI).

Enoch told the BBC that he was motivated to solve the problem after being encouraged by his students, adding that he had no financial motivation for doing so.

The university where he teaches issued this statement:

Dr Enoch first investigated and then established the claims of Riemann. He went on to consider and to correct the misconceptions that were communicated by mathematicians in the past generations, thus paving way for his solutions and proofs to be established.

He also showed how other problems of this kind can be formulated and obtained the matrix that Hilbert and Poly predicted will give these undiscovered solutions. He revealed how these solutions are applicable in cryptography, quantum information science and in quantum computers.

A spokesperson for CMI is quoted in The Telegraph as saying: “As a matter of policy, the CMI does not comment on solutions to the Millennium Problems”

Over at the Aperiodical blog, Katie Steckles and Christian Lawson-Perfect have expressed their skepticism, saying the Riemann Hypothesis has most assuredly not been solved. They write:

Unfortunately, it looks like in this case it’s not a real proof of the Riemann Hypothesis, and this post on a Nigerian discussion forum says emphatically he has not solved it. As mentioned in that post, there’s a paper on academia.edu under his name, which is actually a copy of a paper by someone called Werner Raab (retired). Raab’s website – http://ift.tt/1l3bmSs is empty, and has a single broken link to “the truth of the Riemann hypothesis”. Some digging reveals that that URL has never worked. Confusingly, Enoch seems to be gathering papers about the Riemann Hypothesis on academia.edu under his own name.

The “proof” was presented at this legitimate academic conference (yes, the URL is “computer-conference-site.com”) which does appear to have taken place – although the photos don’t seem to show the kind of turnout you’d expect for presenting a result of this magnitude. Here’s the proceedings of the conference (Enoch’s presentation is “A matrix that generates the point spectral of the Riemann Zeta function”). It also looks like the local organiser of the conference is quite a character. (What’s the deal with fuzzy logic and definitely legitimate academic proceedings?)

Steckles and Lawson-Perfect say that the Riemann Hypothesis has not been cracked, but that the method supposedly being used by Enoch is one currently being tried by more well-established researchers.

Sorry, No Aliens! The Navy Test Fires Trident Missile Off The Coast Of California

Sorry, No Aliens! The Navy Test Fires Trident Missile Off The Coast Of California

Reports flooded in today stating that the warning areas off the coast of Southern California—around the Navy’s Pacific Missile Range—would be activated, causing noise issues associated with re-routed LAX operations. Theories flew, some being totally absurd. In the end, it was exactly what it should have been—a Trident submarine-launched ballistic missile test.

Most people go about their lives in Los Angeles with no idea that some of the world’s premier military operating areas lay not far off of their coast, one of which can especially be used for sending ballistic missiles downrange toward the South Pacific.

You can see all these military operating areas in this map, with the elongated one off of Southern California being used long-range missile launches like the Trident D5 launch tonight.

Beyond the fact that Naval Base Ventura County admitting that it was a Trident launch, the tell-tale sign that tonight’s activity was ballistic missile launch was the swirling, almost surreal trail it left as it tore west through the early evening sky.

We have seen these incredible atmospheric rocket launch phenomenons many times before, and each seems to have its own unique flavor.

Here is the the Navy’s official statement on the event from the Third Fleet’s Cmdr. Ryan Perry via Channel 7, an NBC affiliate in San Diego:

“Navy Strategic Systems Programs conducted scheduled Trident II (D5) missile test flight at sea from USS Kentucky, an Ohio Class SSBN, in the Pacific Test Range off the coast of Southern California. The tests were part of a scheduled, ongoing system evaluation test. Launches are conducted on a frequent, recurring basis to ensure the continued reliability of the system. Each test activity provides valuable information about our systems, thus contributing to assurance in our capabilities.

The missile was not armed. Strategic Systems Programs does not routinely announce missile testing. Information regarding the test launch of Trident II (D5) missiles is classified before the launch.”

At this time it is not clear if the warning areas will be activated for more nights this week, or if this test was the objective of closing the airspace, which is now complete. Hopefully there will be more launches with more spectacular photos and video, although those around LAX may have to deal with a little more jet noise than normal in the process.
