INNUMERACY VII John Hush 2024-01-13 | Now Mr. John Hush calculates the same probabilities as in the last video by doing it the more direct but much harder way. It's a lot more interesting and certainly a lot more fun!
INNUMERACY VI John Hush 2024-01-12 | Mr. John Hush calculates a couple probabilities involving a die or two dice rolled four times each that French gambler and mathematician Antoine Gombaud asked fellow mathematician Blaise Pascal in around 1650 AD or CE. There are two ways of evaluating these probabilities; one is easy, one is hard. This video deals with the easy, indirect method. The next video will evaluate it the harder, direct way.
NUMERACY II: factoring 2024 John Hush 2024-01-02 | Mr. John Hush factors the Happy New Year 2024 as is his annual custom but he writes down a small mistake (although he didn't say the mistake). See if you can spot the typo! Good eye if you do.
NUMERACY I: Todays date is 123123 John Hush 2024-01-01 | On this last day of 2023, Mr. John Hush points out that today's date is 123123. How so?

Synopsis of Arequipa Medical Project John Hush 2023-08-10 | This brief video was created by cataract surgeon John W. as he waited at the airport for his return flight to Canada! Nonetheless, he covers most of the events that took place. Kudos, John!
Volunteer Medical Project in Arequipa John Hush 2023-08-09 | This video was an inspirational, daily occurrence at the beginning of each day at the school where the vision clinic took place. Mr. John Hush helped assess people's distance and near vision. Mrs. Louise Hush was in charge of the operating room at a nearby hospital. Pastor Asdrubal, Project Coordinator Tania and Clinic Supervisor Adriana are in the thumbnail.There were 3000+ patients (less than 5% required no service), 1570 (mostly used) prescription glasses, 600+ stock reading glasses, almost 700 sunglasses (UV is high there), over 200 eye procedures (mostly cataract surgeries), 550 dental patients receiving 640 treatments, as well as almost 70 pediatric eyecare patients the second week including 9 strabismus procedures.It was a pleasure to serve the Lord in this way. The Peruvians were so appreciative. To God be the Glory!
Center of Mass demo in Arequipa, Peru John Hush 2023-08-08 | Mr. John Hush came across these two artistic performers on a street corner in Arequipa, Peru. Notice that the man holding up the other is leaning back on an angle. They are stable due to their center of mass.This demo is similar to the wine bottle holder that lies on an angle. See here: google.com/imgres?imgurl=millersville.edu/physics/experiments/030/botl0.gif&imgrefurl=millersville.edu/physics/experiments/030/&h=421&w=380&tbnid=C8BWVccua9bwbM&tbnh=130&tbnw=117&usg=AI4_-kT0SmSsWU_uXtU3TNZVjQKStZS7Og&vet=1&docid=4L8eP3vKDBuIUMMr. John and his wife Louise were in Arequipa for two weeks volunteering in an eye surgery, eyeglasses and dental medical mission recently with the organization Medical Ministry International (MMI). Louise was in charge of the operating room, mostly for cataracts; John was helping determine people's near and far vision prior to further evaluation.

Mr. John Hush begins by briefly talking about the number of possible positions in a Rubik's cube. Then he estimates the amount of human blood in the world and at what depth it could bury the city of Toronto, Ontario, Canada.
INNUMERACY I John Hush 2023-07-17 | Mr. John Hush begins a new series based on the 1988 book entitled INNUMERACY by John Allen Paulos, a retired professor of mathematics from Temple University in Philadelphia. In this first episode, he discusses how people are not very good at comprehending big numbers. Try your hand (mind?!) at estimating the requested quantities.

A Cat With Good Table Manners John Hush 2023-05-06 | Foster cat Blythe returns! She displays polite and proper table manners as she drinks water. Mrs. Louise Hush says "strange behaviour". Mr. John Hush follows with "smart". It reminds me of chapter 7 of the book of Judges in the Old Testament.
The Rhythms of Logarithms. Part 12 John Hush 2023-05-02 | Mr. John Hush simplifies a logarithmic expression that doesn't appear to be simplifyable (if that's even a word!). See if you can do it yourself prior to him showing you how.
The Rhythms of Logarithms. Part 11 John Hush 2023-05-01 | In this last (?) video, Mr. John Hush looks at three applications of logarithms in the real world: 1. acids and bases, 2. sound and 3. earthquakes.
Hang On For Dear Life! John Hush 2023-04-21 | Our other recent foster cat, Mattie, decides not to let go when picked up. She and Blythe (in a recent video) were rescued from a hoarding situation with six other cats. They are adapted nicely after a difficult first week. Mattie had to be shaved because she had so much matted (hence her new name Mattie) fur due to the filth on her.
The Rhythms of Logarithms. Part 10 John Hush 2023-04-19 | Mr. John Hush now uses an exponential equation to solve for various quantities. He uses a log(arithm) for one part.

The Rhythms of Logarithms. Part 6 John Hush 2023-04-06 | Mr. John Hush now uses the law of logarithms for a power to solve a couple exponential equations. First he points out that this law is equivalent to the exponential law for raising a power to another exponent.
The Rhythms of Logarithms. Part 5 John Hush 2023-04-05 | Mr. John Hush proves that log x^n = n log x to any base, where x^n is x to the n. Then he proves, using this fact, that y = 2^x and y = log2 x are inverse functions, where the 2 in log2 x indicates that the base of the log is 2. The base of 2 can be replaced with any permissible base, b. Generally, b is greater than zero and not 1).

Curves are straight? Opt. Illusion #18 John Hush 2023-03-22 | Although the shapes are curved, from a distance and at a certain angle they look straight. So there appears to be a triangle at the end of the video.
Its not really there! Optical Illusion #17b John Hush 2023-03-22 | This is another video of the same illusion.
A Real Image! Optical Illusion #17a John Hush 2023-03-22 | The image of the light bulb is made by a concave mirror that's out of sight. The actual light bulb is upside down. It looks like it's really there so we say it's a real image but it isn't really there!
In Motion? No! Optical Illusion #16 John Hush 2023-03-22 | There seems to be motion, especially in the circles, in this still image! From the Museum of Science in Boston. And, no, it's not my camera that was moving around!
Same reds & blues! Optical Illusion #15 John Hush 2023-03-22 | The reds making up the X on the left look different because the apparently lighter red line is next to white squares while the apparently darker red is next to blue squares. Similarly for the two blues making up the X on the right.
Moving in and out! Optical Illusion #14 John Hush 2023-03-22 | Study the orientations of the spirals then see what seems to happen when they rotate. Another example from the Boston Museum of Science.

Inequalities (Its NOT fair!). Part 1 John Hush 2023-03-02 | Mr. John Hush begins a new series on solving inequalities. It's harder than solving equations. He solves both a linear and a quadratic inequality.
Whats Your (Trig.) Identity? Part 5 John Hush 2023-02-27 | Mr. John Hush now uses the trick of multiplying one side by the conjugate of its denominator divided by the same quantity (which equals 1 of course and so is fine). He also shows an alternate solution which is also perfectly fine but is not allowed by many math teachers.
Whats Your (Trig.) Identity? Part 4 John Hush 2023-02-27 | Mr. John Hush proves two more-difficult-looking trigonometric identities. It isn't always clear what to do so just try something logical and see what happens.
