File:Johannes Kepler 1610.jpg|<!--[[کپلر]] (1571–1630): used the accurate observations of [[Tycho Brahe]] to formulate [[کیپلر قوانین برائے سیاروی حرکت]], described elliptical motion of planets around the sun, developed early telescopes, invented the convex eyepiece, discovered a means of determining the magnifying power of lenses.-->
File:Evangelista Torricelli2.jpg|<!--[[Evangelista Torricelli]] (1608–47): invented the [[بھارپیما]] (a glass tube of [[پارہ]] inverted into a dish), found that the change of height of the mercury each day was from [[ہوا کا دباؤ]], worked in [[ہندسہ]] and developed [[تکامل]], published findings on fluid and projectile motion in his 1644 ''Opera Geometrica'' (Geometric Works)-->
File:Blaise pascal.jpg|<!--[[پاسکل]] (1623–62): experimented with [[سیال (مادہ)]]s, formulated [[Pascal's law]] in the 1650s stating that the [[دباؤ]] applied to a fluid taken in a closed container is transmitted with equal force throughout the container, proved that air has weight and that air pressure can produce a [[فراغ]], namesake of the unit of pressure: the [[
File:Christiaan Huygens-painting.jpeg|<!--[[Christiaan Huygens]] (1629–95): studied the [[حلقہ ہائے زحل]] and discovered its moon [[Titan (moon)|Titan]], invented the [[pendulum clock]], studied [[بصریات]] and [[centrifugal force]], theorized that light consists of [[موج]]s ([[Huygens–Fresnel principle]]) which became instrumental in the understanding of [[wave-particle duality]].-->
File:13 Portrait of Robert Hooke.JPG|<!--[[Robert Hooke]] (1635–1703): formulated the [[Hooke's law|law of elasticity]], invented the balance spring, the spiral spring wheel in watches, the Gregorian telescope, and the first screw-divided quadrant, constructed first arithmetical machine, improved cell theory with the microscope-->

File:Georg Simon Ohm3.jpg|<!--[[جارج سائمن اوہم]] (1789–1854): found that there is a direct proportionality between the [[برقی رو]] I and the potential difference ([[وولٹیج]]) V applied across a conductor, and that this current is inversely proportional to the [[برقی مزاحمت]] R in the circuit, or I = V/R, known as [[قانون اوہم]], namesake of the unit of electrical resistance (the [[اوھم]])-->
File:Faraday-Millikan-Gale-1913.jpg|<!--[[مائیکل فیراڈے]] (1791–1867): showed how a changing magnetic field can be used to generate an electric current ([[قانون فیراڈے لینز]]), applied this knowledge to the development of several electrical machines, described principles of [[electrolysis]], early pioneer in the field of low temperature study-->
File:Cdoppler.jpg|<!--[[Christian Doppler]] (1803–53): first described how the observed frequency of light and sound waves is affected by the relative motion of the source and the detector, a phenomenon which became known as the [[
File:Joule James sitting.jpg|<!--[[جیمز پریسکوٹ جول]] (1818–89): discovered that heat is a form of [[توانائی]], ideas led to the theory of [[قانون بقائے توانائی]], worked with [[William Thomson, 1st Baron Kelvin|Lord Kelvin]] to develop the absolute scale of [[درجہ حرارت]], made observations on [[magnetostriction]], found the relationship between current through [[مزاحم]] and the heat dissipated, now called [[Joule's first law|Joule's law]].-->
File:Lord Kelvin photograph.jpg|<!--[[William Thomson, 1st Baron Kelvin]] (1824–1907): major figure in the history of [[حرحرکیات]], helped develop law of conservation of energy, studied wave motion and vortex motion in [[سيالی حرکيات]] and produced a dynamical theory of heat, formulated of the [[first law of thermodynamics|first]] and [[حرحرکیات کا دوسرا قانون]]-->
