Once assembled, a working instrument is created for \u003cb\u003emultiplying, dividing, amplifying and calculating elements\u003c\/b\u003e. The DIY logarithmic slider shows that mathematics can be practical, tactile, and understandable. The AstroMedia folding model will work well at home, school and in the collection of a lover of old scientific instruments. It’s a small construction project that \u003cb\u003eteaches accuracy, scale reading, and logical thinking\u003c\/b\u003e. The finished slider allows you to count without batteries, electricity and screen.\u003c\/p\u003e\u003cp\u003eThe AstroMedia logarithmic slider refers to an instrument that \u003cb\u003efor many years was the primary tool of students, technicians, engineers and scientists\u003c\/b\u003e. Before electronic calculators became commonplace, similar sliders helped to quickly perform the calculations needed in design, construction, navigation and technical work.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eThis AstroMedia folding model is not just a decoration\u003c\/b\u003e. After gluing, it becomes a \u003cb\u003efunctional device\u003c\/b\u003e with a movable middle part and a foil window, i.e. a cursor. The user can move scales, set values, and read results as they have done for decades in schools and technical laboratories.\u003c\/p\u003e\u003cp\u003eThe logarithmic slider AstroMedia uses logarithmic scales, i.e. those at which distances correspond to the logarithms of numbers. Thanks to this, multiplication can be replaced by adding distances on a scale, and dividing them – subtracting them. How do you do that?\u003c\/p\u003e\u003cp\u003e\u003cb\u003e▶ Setting the number 1 on a moving scale. \u003c\/b\u003e The user sets “1” on the tongue of the moving middle element at the first number of actions. This prepares the slider for calculation and shows that the result depends on the mutual position of the two scales.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e▶ Finding the second number. \u003c\/b\u003e Then, on a moving scale, a second value is searched, for example, a second multiplication factor. The shift in scale means that distances representing both numbers are “added” in a logarithmic sense.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e▶ Reading the result on a fixed scale. \u003c\/b\u003e The result is read on a constant scale under the set value. The DIY logarithmic slider does not show the result digitally, so the user also learns to estimate the order of magnitude.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e▶ Performing division. \u003c\/b\u003e When dividing, the divider is set relative to the brave. Then the distances on the scale are subtracted, and the result can be read in the right place.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e▶ Powers and elements. \u003c\/b\u003e When amplifying and elementing, appropriate relationships between scales are used. Thanks to this, the logarithmic slider AstroMedia helps to understand that mathematical actions have their geometric representation.\u003c\/p\u003e\u003ch2\u003eExamples of calculations\u003c\/h2\u003e\u003cp\u003eThe logarithmic slider AstroMedia is best explored using simple examples.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e✖ If you want to multiply\u003c\/b\u003e 2 × 3, set the “1” moving scale at the number 2 on a fixed scale, then find 3 on a moving scale and read the result under this value.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e➗ When dividing\u003c\/b\u003e, for example 6 : 3, set 3 from the moving scale at 6 on a fixed scale, and read the result at the “1” moving scale.\u003c\/p\u003e\u003cp\u003eThe AstroMedia \u003cb\u003efolding model also allows you to practice orientation calculations\u003c\/b\u003e, because the slider shows not only the result itself, but also indicates whether the answer is larger, smaller and to what extent it should fit.\u003c\/p\u003e\u003cp\u003eIt is important to calmly move the middle part and accurately set the cursor. The DIY logarithmic slider requires careful looking at the scale, which is why \u003cb\u003edevelops precision, patience and awareness of the value of numbers\u003c\/b\u003e.\u003c\/p\u003e\u003ch2\u003eThe slide rule and its early uses\u003c\/h2\u003e\u003cp\u003eThe history of the slide rule begins after the invention of logarithms. \u003cb\u003eThe Encyclopedia Britannica\u003c\/b\u003e states that Edmund Gunter developed an early logarithmic scale used by sailors, among others, and that William Oughtred created the first adjustable instrument of this type in 1632.\u003c\/p\u003e\u003cp\u003eOver the following centuries \u003cb\u003e, the slide rule became one of the most important computational tools\u003c\/b\u003e . Before the 1970s In the 1920s, it was a very common work tool for scientists and engineers, and its scales allowed them to perform multiplication, division, square roots, exponentiation, calculate proportions and solve trigonometric problems.\u003c\/p\u003e\u003cp\u003eAstroMedia slide rule gives the user access to a tool that \u003cb\u003ehas long helped design bridges, machines, structures and devices\u003c\/b\u003e . This is a good opportunity to show the student that ancient technology was not primitive, but was based on clever, precise solutions.\u003c\/p\u003e\u003ch2\u003eThe AstroMedia folding model and its educational value\u003c\/h2\u003e\u003cp\u003eThe AstroMedia folding model shows mathematics in a different way than a notebook and calculator. The user first assembles the instrument and then independently checks how the location of the scales affects the result of the calculation.\u003c\/p\u003e\u003cp\u003eThe DIY logarithmic slider works well as a learning aid because it combines manual work with practical counting. The AstroMedia \u003cb\u003e logarithmic slider can be used in math lessons, technology history or during homeschooling with a child\u003c\/b\u003e.\u003c\/p\u003e\u003ch2\u003eWho will this model be suitable for?\u003c\/h2\u003e\u003cp\u003eThe AstroMedia logarithmic slider will be a good choice for students, teachers, parents, math lovers and people interested in old tools. It is also a suitable gift for someone who likes unusual scientific aids and wants to understand how analog counting works.\u003c\/p\u003e\u003cp\u003eThe AstroMedia folding model is small, lightweight and quick to assemble compared to more extensive kits. The construction time is \u003cb\u003eabout 1 to 3 hours\u003c\/b\u003e, so the set will work when you are looking for a shorter educational project. The finished slider has dimensions \u003cb\u003e287 × 40 × 4 mm\u003c\/b\u003e, and the \u003cb\u003eset contains Polish-language instructions for building and performing calculations\u003c\/b\u003e.\u003c\/p\u003e\u003ch2\u003eList of components of the set\u003c\/h2\u003e\u003cp\u003eThe set includes:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e✔ 2 sheets of die-cut cardboard with elements for building a slider,\u003c\/li\u003e\n\u003cli\u003e✔ film for making a movable window,\u003c\/li\u003e\n\u003cli\u003e✔ \u003cb\u003ePolish-language construction instructions\u003c\/b\u003e,\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e✔ instructions for performing basic calculations\u003c\/b\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eDuring assembly, universal glue, sharp knife, scissors, ruler and adhesive tape can be useful.
