- The Pentium contains a complicated circuit to multiply by three (righto.com)
In 1993, Intel released the high-performance Pentium processor, the start of the long-running Pentium line. I’ve been examining the Pentium’s circuitry in detail and I came across a circuit to multiply by three, a complex circuit with thousands of transistors. Why does the Pentium have a circuit to multiply specifically by three? Why is it so complicated? In this article, I examine this multiplier—which I’ll call the ×3 circuit—and explain its purpose and how it is implemented.
- Heat death of the universe (Wikipedia)
The heat death of the universe (also known as the Big Chill or Big Freeze) is a hypothesis on the ultimate fate of the universe, which suggests the universe will evolve to a state of no thermodynamic free energy, and will therefore be unable to sustain processes that increase entropy. Heat death does not imply any particular absolute temperature; it only requires that temperature differences or other processes may no longer be exploited to perform work. In the language of physics, this is when the universe reaches thermodynamic equilibrium. The Heat Death theory has become the leading theory in the modern age with the fewest unpredictable factors.
