While registered dietitians certainly recommend balance, variety, and moderation to ensure you get all the necessary nutrients that you need, they have personal superfoods that they reach for on a regular basis for both nutrition and convenience purposes. From turmeric smoothies to chocolate and peanut butter combos, dietitians around the country share the foods they eat every single day.

The big test event..

My function needs mass testing. It would apperar as if I have come up with an algorithm that is faster than the standard PrimeQ function with regards to detecting a prime but not faster if the number being tested is quickly discovered to not be prime by the standard test. thus if after further testing and prooving my function is completly accurate then it probably should work in conjuction with the standard PrimeQ function in order to attain an optimal.

well here is test away.

 PrimeQu[cex_] := Catch[ Module[ {zcv = PowerMod[2, cex, cex] - 2, zcv2 = JacobiSymbol[ FromDigits[Append[Table[1, {xvc, Floor[Log[2, cex]] + 1}], 0], 3] FromDigits[ Append[Table[1, {xvc, Floor[Log[3, cex]] + 1}], 0], 2], cex], zcv3 = JacobiSymbol[ FromDigits[Append[Table[1, {xvc, Floor[Log[2, cex]] + 1}], 0], 5] FromDigits[ Append[Table[1, {xvc, Floor[Log[5, cex]] + 1}], 0], 2], cex], Var25, Var26, ced = cex }, Var25 = If[GCD[ced, 2] == 2 || GCD[ced, 3] == 3 || GCD[ced, 5] == 5, If[ced == 2 || ced == 3 || ced == 5, 1, 2], 1]; Var26 = If[zcv == 0 && Abs[zcv2] == 1 && Abs[zcv3] == 1, 1, 2]; If[Var25 == 1 && Var26 == 1, Throw["True"], Throw["False"]]; ]];

I've started making youtube videos about maths, here's a link to my second video. I hope you enjoy, and I hope to receive feedback.

+Marele Lup Alb, oh yes, I forgot to say but about 45s into the video you should hear me say the p/q is in its simplest form.

Sorry if that hindered your viewing process at all.

If you want to look at some higher level mathematics you're free to check out my video on proof of differentiation by first principle. It is the first in a series of proofs which will look at all of the differentiation in the A-level Maths and Further Maths syllabus. The video series will be completed over the summer, once my exams are finished.

I have renewed respect for mathematicians who devote their abilities  to providing us with information , in the form of statistics or calculations ,which  give us the tools for  everything from safe bridges to the  precise measurements we need to survive in our own environment. Their skills develop appropriate dosages for medicine, and are blueprints for more than construction projects.
MATH MEN ARE THE BEST. I am curious to know whether
  fracking is perhaps the  cause of the leak problem?  Okalhomans are saying since fracking began they have earthquakes, do they frack in New Mexico.
What kind of world wants more production of a substance so toxic  some of the elements have been radioactive since before the solar system was formed. We use energy produced by substances which can kill us, Cherynoble is one example Fukashima another, Three Mile Island almost became a national disaster, mining is also a risk made worse by fracking

When we will  use more solar?
OKLAHOMA CITY – While being played down and barely even reported in the national media, a fairly serious radiological event occurred at the Waste Isolation Pilot Plant, a federally-operated nuclear waste repository 26 miles northwest of Carlsbad, New Mexico on Feb. 14, 2014.

Sorry, if you're going to be posting this drivel in a mathematics community, then you're going to have to accept counter-arguments based on mathematics.

Mathematically, nuclear power is safer than solar. Yes, that's right. Nuclear power is safer than solar power. It's actually about five times safer. The numbers are at http://www.forbes.com/sites/jamesconca/2012/06/10/energys-deathprint-a-price-always-paid/

No person worldwide has died in a civilian nuclear accident in the last fifteen years. This is for an energy source that supplies one sixth of electricity generation worldwide. No other energy source has a 15-year worldwide streak of perfect safety.

The correct solution to the nuclear waste problem is to reprocess the fuel. Reprocessing converts waste into usable fuel. It's more expensive, but it eliminates waste. You can in fact recapture all the waste and turn it back into fuel. Unfortunately, reprocessing was banned by the Carter administration for poltiical reasons (it makes it slightly easier to manufacture nuclear weapons). We need to stop allowing political interests to drive scientific policy.

A good application of heavy maths... Have a look at my newes post! Cheers!
Randomness. A magic that happens behind the scene. An incomprehensible little blackbox that does the job for us. Quants. Many use it every day without thinking, without considering how those beautifully uniformly distributed numbers are drawn?! Why so fast? Why so random? Is randomness a byproduct

What is renormalization in quantum field theory (QFT). I've been told (a Leonard Sussink video) that renormalization is the process of being able to ignore scales (in an integral, for example) that are so small that it would cause integrals to not converge. Is there a more mathematical description of this?

Although the Four Colour Theorem is old hat, we give a simple model-theoretic proof that visually illustrates why four colours suffice to chromatically differentiate any set of contiguous, simply connected, and bounded planar spaces:

Dear Zheng

Thanks for drawing my attention to Barua's article.

Barua's perspective appears to reflect that of professional mapmakers down the centuries, who have intuitively known on the basis of experience---essentially for all the reasons and arguments highlighted by Barua---that every planar map they have encountered is 4-colourable.

The challenge has been to extend what is intuitively known beyond reasonable doubt---on the basis of finite experience---into a formal proof that applies to all possible planar maps beyond mathematical doubt.

As Layra points out, Barua does not appear to address the latter doubt.

Regards,

Bhup

Need help please!!!
i want to find the probability of having a pair, straight and the other hands in a 5 card poker game with the condition that there are 2 players... each player gets 5 cards... 1st player has a pair and for the other we don't care... thanks in advance...
