The Clay Mathematics Institute officially designated the title Millennium Problem for the seven unsolved mathematical problems, the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, Yang–Mills existence and mass gap, and the Poincaré conjecture at the ...
The second section is the most expensive section of the entire motorway due to unfavourable terrain, requiring the construction of many tunnels and bridges.

It includes only projects that are underway or completed. Additionally, projects with multiple independent segments (e.g., I-69 Indiana-Texas Extension, Trans-Texas Corridor) are not included, though individual segments may or may not make the list. Costs shown below exclude financing costs.
Goldbach’s Conjecture. One of the greatest unsolved mysteries in math is also very easy to write. Goldbach’s Conjecture is, “Every even number (greater than two) is the sum of two primes ...
This machine used the decimal number system and was powered by cranking a handle. The British government was interested, since producing tables was time-consuming and expensive and they hoped the difference engine would make the task more economical. [7] In 1823, the British government gave Babbage £1700 to start work on the project.

The history of mathematics deals with the origin of discoveries in mathematics and the mathematical methods and notation of the past. Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales.
More expensive cities can push that cap as high as one-third of a person’s total income, Sethi said, but “you are incurring massive risk particularly if one person loses their job or something ...
