A major advance towards the twin prime conjecture. 0000062364 00000 n 0000093483 00000 n He proved that there are an infinite number of pairs of consecutive primes that differ by some n less than about 70,000,000. 0000038960 00000 n It's similar to Fermat's Last Theorem; the theorem itself is just a cool fact about numbers, but the proof used a new theorem called the Modularity Theorem which allows us to better understand objects called elliptic curves, which are also important in fields like cryptography. 0000056548 00000 n But why? 0000080903 00000 n In mathematics, however, a similar result can bring you international acclaim. If it is ever solved, what other problems in mathematics would be affected? The upper bound has been improved to 246 according to Wikipedia, so the best we know is that either there are infinitely many primes that differ by 2, or there are infinitely many primes that differ by 4, or 6, or...., or 246. 0000071109 00000 n 0000005433 00000 n 0000057159 00000 n trailer 0000063609 00000 n 0000018248 00000 n �+D�@�����v�r��?�3��?\�?�?X�Pϲ��Aj�� #��5���,�!R,�v54020�e����a�t/�,�3�;�/(+W9Lf������=�h��� k>��`;( ���(�p]dS��N+�6�N�}LL;���2X1. Cryptography is the basis of the internet, our money system, and just about everything else in our economy. 0000003762 00000 n 0000047891 00000 n Primes are important for cryptography. Want facts and want them fast? This is the case with recent progress towards the famous twin prime conjecture. New research shows that ventilation is crucial and that masks are effective. All our COVID-19 related coverage at a glance. The first version states that there are an infinite number of pairs of twin primes (Guy 1994, p. 19). Roger Penrose, Reinhard Genzel and Andrea Ghez win the 2020 Nobel Prize in Physics for their work on black holes. This could cause changes in cryptography which would then flow on to the rest of everything. Twin primes are specifically prime numbers that differ by 2. 0000091358 00000 n 0000018516 00000 n '�����y�T����d�mw���I ��A����=} 0000005091 00000 n There are two related conjectures, each called the twin prime conjecture. There's been progress on one of the biggest open problems in maths: the twin prime conjecture.

We talk to three of this year's winners of the prestigious Whitehead Prizes. This year has seen a flurry of results as mathematicians hunt down the elusive proof of the twin prime conjecture. 0000077144 00000 n Yitang Zhang proved that there are an infinite number of pairs of primes that differ by n, where n is some number less than 70 million or so. 0000093614 00000 n The question arose: can we close the gap? A twin prime is a prime number that is either 2 less or 2 more than another prime number—for example, either member of the twin prime pair (41, 43). Can Dan Goldston and Cem Yalcin Yildrim repair the hole in their proof to make the biggest breakthrough in prime number theory for 80 years?
