Practice Questions 16 to 20 Slide Rules and Mathematics 2024-04-17 | In this challenging set of questions we introduce a new slide rule, the Aristo Studio Model 0968 (the 10 inch version of the 20" AS Slide Rule). This has a different placement of scales, so we concentrate on deliberately planning out our scale use and developing fluency going between scales and sides of the rule.The Aristo Studio 0968 is a $20-30 slide rule that features both the B scale and the K scale on the slide, as well has having a P scale for cosines and advanced functions. It is a thick plastic slide rule with a large cursor and a really good feel in the hand and is one of my favorites.Remember to hit 'Like' and 'Subscribe', your support of this channel is appreciated.Join our Discord Channel at discord.gg/QwcFct7DWc Help the Channel by joining our channel as a memberPatreon- patreon.com/bobthescienceguyor sending a Paypal for equipment (I do take requests for content)paypal.com/donate?hosted_button_id=ED65DTMU9AB8C

Entropy and Work Slide Rules and Mathematics 2022-02-01 | Science deniers like to point to the Second Law of Thermodynamics in their claim an atmosphere cannot exist next to the vacuum of space. This is just a recycled anti-evolution argument. In this video, we look at the effect of work on entropy and how to counter these arguements.Remember to hit 'Like' and 'Subscribe', your support of this channel is appreciated.Join our Discord Channel at discord.gg/QwcFct7DWc Help the Channel by joining our channel as a memberPatreon- patreon.com/bobthescienceguyor sending a Paypal for equipment (I do take requests for content)paypal.com/donate?hosted_button_id=ED65DTMU9AB8C
A Discussion of Time Part 1 Slide Rules and Mathematics 2022-01-27 | Today I begin a two part series on Time and the Astrolabe with mention of sundials. We are covering the equation of time and changes in time with longitude due to the rotation of earth and the earth's orbit about the sun.Remember to hit 'Like' and 'Subscribe', your support of this channel is appreciated.Join our Discord Channel at discord.gg/QwcFct7DWc Help the Channel by joining our channel as a memberPatreon- patreon.com/bobthescienceguyor sending a Paypal for equipment (I do take requests for content)paypal.com/donate?hosted_button_id=ED65DTMU9AB8C
The Saros Cycle- The Lunar Eclipse Slide Rules and Mathematics 2022-01-26 | The Saros Cycle is the interactions between the various orbital periods of the moon (sideral, node to node, phase to phase, etc) to determine the timing of lunar eclipses.
Astrolabe | Design and Parts Slide Rules and Mathematics 2022-01-25 | Initially designed around 200 BC, the Astrolabe is an analog computer based on a Geocentric Solar System. The iPhone of its day, the design reached its pinnacle around 800AD in the Islamic World. It was well known amongst the educated classes and mariners in the Middle Ages.In this episode we will discuss the construction and parts of the Astrolabe, using both a precision brass model and a wooden one I built from a kit. We will discuss the Zodiacal Calendar, Modern Calendar, the Equinox and Solstice and how to sight a celestial body, tell the time of day, and calculate the time of dawn. First of a multipart series on Slide Rules and Mathematics.This was taken from a live stream presentation on 'Common Sense Science' and edited with new material. Note, the focus in this is off a bit- it is automatic and not adjustable (nor can it be fixed so it changes when I put my hands in the field of view). But I did include clear photos so listen to the description I give and there will be a clear photo to review shortly.Remember to hit 'Like' and 'Subscribe', your support of this channel is appreciated.Join our Discord Channel at discord.gg/QwcFct7DWc Help the Channel by joining our channel as a memberPatreon- patreon.com/bobthescienceguyor sending a Paypal for equipment (I do take requests for content)paypal.com/donate?hosted_button_id=ED65DTMU9AB8C
Bob Measures the Curve Slide Rules and Mathematics 2022-01-21 | Measuring the curve of the earth is a challenge for the average person. You have to design a test that will give you a yes or no, and then there is a question precision. In this video, I devise a test to demonstrate the curve of the earth over the 2500 feet of lake in my back yard using an auto level.This is the outline of the entire observation, with all data and the method used to demonstrate a compelling case for curvature.Remember to hit 'Like' and 'Subscribe', your support of this channel is appreciated.Join our Discord Channel at discord.gg/QwcFct7DWc Help the Channel by joining our channel as a memberPatreon- patreon.com/bobthescienceguyor sending a Paypal for equipment (I do take requests for content)paypal.com/donate?hosted_button_id=ED65DTMU9AB8C

Selecting a Slide Rule- Advanced and Specialty Rules Slide Rules and Mathematics 2022-01-17 | Here we pull out the stops with the Fuller Calculator and the Faber Castell N 2/83. We examine 20 inch slide rules and pocket rules, comparing the accuracy of the rules and the relation to the length of the slide rule.We also have a look at the E6B and other aviation slide rules and military slide rules for aiming howitzers.Remember to hit 'Like' and 'Subscribe', your support of this channel is appreciated.Here are some useful slide rule links....The International Slide Rule Museum-sliderulemuseum.comVirtual Slide Rule on line-http://www.antiquark.com/sliderule/simJoin our Discord Channel at discord.gg/QwcFct7DWc Help the Channel by joining our channel as a memberPatreon- patreon.com/bobthescienceguyor sending a Paypal for equipment (I do take requests for content)paypal.com/donate?hosted_button_id=ED65DTMU9AB8C
Mother of all Slide Rules- The Fuller Calculator Slide Rules and Mathematics 2022-01-14 | Why a Fuller Calculator?A slide rule is a mechanical calculator which was the defining characteristic of the mid-20th Century engineer. While it is a very useful tool, allowing us to visualize the relationship between numbers, it does have a drawback- accuracy. A standard slide rule is accurate to 3 significant digits. Advanced slide rules such as the Faber Castell N 2/83 can be pushed to 4 digits, as can 20 inch slide rules. For the ultimate in accuracy, the Fuller Calculator with its 500 inch spiral scale, can easily go to 5 significant figure and will allow you to even get to 6 if the analog gods are with you.Thank you to all the patreons, pay pal donations and channel memberships to enable me to obtain this rare slide rule from a small shop in the UK, and to Fight the Flat Earth for accepting delivery and forwarding it on to me in the US as they would not ship internationally.Remember to hit 'Like' and 'Subscribe', your support of this channel is appreciated.Join our Discord Channel at discord.gg/QwcFct7DWc Help the Channel by joining our channel as a memberPatreon- patreon.com/bobthescienceguyor sending a Paypal for equipment (I do take requests for content)paypal.com/donate?hosted_button_id=ED65DTMU9AB8C
