Question 1: Recently the PLC Tenors' Association's 7 members gave a concert at the city tradeshow. Each tenor sang a duet with every other tenor. How many duets were there?
A- 21
Tenor 1 sings with tenors 2, 3, 4, 5, 6 & 7 = 6 duets. Tenor 2 has already sung with tenor 1 = 5 more duets. And so the remaining duets decrease in steps of 4, 3, and 2, to 1.

Question 1
Q- Who invented Network Time Protocol (NTP?)
A- NTP was designed by David L. Mills in 1985. NTP (and variations) are still in use today.
A quick Wikipedia reference- The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. NTP is intended to synchronize all participating computers to within a few milliseconds of Coordinated Universal Time (UTC). It uses the intersection algorithm, a modified version of Marzullo's algorithm, to select accurate time servers and is designed to mitigate the effects of variable network latency. NTP can usually maintain time to within tens of milliseconds over the public Internet, and can achieve better than one millisecond accuracy in local area networks under ideal conditions.
Many PLCs feature NTP or a less complex implementation SNTP (Simple Network Time Protocol.

Trivia
Q- Annular, total, partial and hybrid are all types of what? (Astronomy)
A- Solar Eclipses
Total solar eclipse occurs when the Moon completely covers the Sun, as seen from Earth.
Partial solar eclipse happens when the Moon only partially covers the disk of the Sun.
Annular solar eclipse occurs when the New Moon covers the Sun's center, leaving its outer edges to form a “ring of fire” or annulus.
Hybrid solar eclipse is a rare form of a solar eclipse, which changes from an annular to a total solar eclipse, and vice versa, along its path.
Total Eclipse of the Heart- song released by Bonnie Tyler in 1983 and still has one of the weirdest film clips of all time.
Visual Conundrum
Hint- Name of a Famous Scientist/ Mathmatician
Answer- Ada Lovelace
Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and to have published the first algorithm intended to be carried out by such a machine. As a result, she is often regarded as the first computer programmer.

The image on the right is ACE or the Advanced Composition Explorer which observes and measures magnetic fields and particles in space, from a vantage point approximately 1/100 of the distance from Earth to the Sun. Lauched in 1997, The ACE spacecraft was designed and built at the Johns Hopkins University Applied Physics Laboratory, in Laurel, MD. The structure has two octagonal decks, 5.25-feet across and 3.2-feet high, with an overall wingspan of about 27 feet. The spacecraft, which rotates at five revolutions per minute, is stabilized with the spin axis pointing from the Sun to Earth. Using four deployable solar panels and a nickel-cadmium battery, the spacecraft has a peak power of 443 watts ⎯ similar to the power consumption of a fridge.
ACE orbits the L1 Lagrange point, which is a point of gravitational equilibrium between Earth and the Sun, about 900,000 miles from Earth and 92 million miles from the Sun. This orbit affords ACE a prime location in the solar wind flow that heads toward Earth.
ACE launched with nine instruments ⎯ eight of which are still operating ⎯ designed to observe the wide range of particles in space, differentiating between various elements, energies, and charges.

Trivia
Q- How much memory did the computer on the Apollo 11 (AGC) have?
A- 15-bit wordlength + 1-bit parity, 2048 words RAM (magnetic-core memory), 36,864 words ROM (core rope memory)
The Apollo Guidance Computer (AGC) is a digital computer produced for the Apollo program that was installed on board each Apollo command module (CM) and Apollo Lunar Module (LM). The AGC provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft.
The AGC has a 16-bit word length, with 15 data bits and one parity bit. Most of the software on the AGC is stored in a special read-only memory known as core rope memory, fashioned by weaving wires through and around magnetic cores, though a small amount of read/write core memory is available.

Trivia
Q- What is the name given to the smallest unit of time successfully measured and recorded??
A- Zeptosecond
A zeptosecond is a thrillionth of a billionth of a second. That's a decimal point followed by 20 zeroes and a 1.
0.000 000 000 000 000 000 001.
According to the BBC, a group of scientists at Goethe University in Germany successfully recorded the zeptosecond. They measured how long it takes for a photon to cross a hydrogen molecule- around 247 zeptoseconds- making this measurement the shortest time span ever recorded.
