The answers to this question are pretty funny, and also fairly informative!
KnIT didn’t read the papers like a scientist – that would have taken a lifetime. Instead, it scanned for information on a protein called p53, and a class of enzymes that can interact with it, called kinases. Also known as “the guardian of the genome”, p53 suppresses tumours in humans. KnIT trawled the literature searching for links that imply undiscovered p53 kinases, which could provide routes to new cancer drugs.
Having analysed papers up until 2003, KnIT identified seven of the nine kinases discovered over the subsequent 10 years. More importantly, it also found what appeared to be two p53 kinases unknown to science. Initial lab tests confirmed the findings, although the team wants to repeat the experiment to be sure.
Mysteriously, the five Platonic solids are almost entirely absent from the history of mathematics and science on the Indian subcontinent, but this gold icosahedron found in Tipoo Sultan’s treasury is an exception.
This is a small, very well crafted icosahedron with a number in East Arabic numerals on each face. It apparently was in the treasury of Tipu Sultan at the time he was overthrown by the British in 1799 at Seringapatam in southern India, but this object may be much older than from the time of Tipu or his father. The origin of this, where it was created and for what purpose appear to have been lost with time.
Paul Bien speculates about the numerals on this artifact, which are the following, arranged as a net unfolded from the solid by cutting some edges:
The total sum of the numbers is 5190. The sum of the numbers on the lid is 3206, leaving the sum of the numbers on the rest of the icosahedron at 1984. From these numbers the structure of the icosahedron yields very close values for the golden ratio, phi= 1.618.
The basic geometric definition of the golden ratio is that the whole is to the larger part as the larger part is to the smaller part. Applying this to the icosahedron, take the whole = 5190, the larger part = 3206, and the
smaller part = 1984:
whole/larger part = 5190/3206 = 1.6188 = 1.0005 * phi
larger part/smaller part = 3206/1984 = 1.6160 = 0.9987 * phi.
There are many more intriguing results including ones for pi, and the square roots of 2, 3, and 5. These results arise in some very simple ways from the icosahedron that appear to leave little room for these results occurring by chance. Also, it appears that the twenty individual
numbers themselves come about from some very clever number play between pi and phi. There’s little doubt that whomever created this had a very deep and insightful mathematical mind.
However, the actual structure and purpose of the object remains a mystery.
