The more important question is "What are your inventions since the day you born?"
Your question has been carefully tailored to exclude all the Amazing and great inventions created by Muslims even further than 500 years.The only reason you are even capable of using a computer is because Muslims invented Algebra .So there !
Around the year 1,000, the celebrated doctor Al Zahrawi published a 1,500 page illustrated encyclopedia of surgery that was used in Europe as a medical reference for the next 500 years. Among his many inventions, Zahrawi discovered the use of dissolving cat gut to stitch wounds -- beforehand a second surgery had to be performed to remove sutures. He also reportedly performed the first caesarean operation and created the first pair of forceps.
Now the Western world's drink du jour, coffee was first brewed in Yemen around the 9th century. In its earliest days, coffee helped Sufis stay up during late nights of devotion. Later brought to Cairo by a group of students, the coffee buzz soon caught on around the empire. By the 13th century it reached Turkey, but not until the 16th century did the beans start boiling in Europe, brought to Italy by a Venetian trader.
Abbas ibn Firnas was the first person to make a real attempt to construct a flying machine and fly," said Hassani. In the 9th century he designed a winged apparatus, roughly resembling a bird costume. In his most famous trial near Cordoba in Spain, Firnas flew upward for a few moments, before falling to the ground and partially breaking his back. His designs would undoubtedly have been an inspiration for famed Italian artist and inventor Leonardo da Vinci's hundreds of years later, said Hassani.
In 859 a young princess named Fatima al-Firhi founded the first degree-granting university in Fez, Morocco. Her sister Miriam founded an adjacent mosque and together the complex became the al-Qarawiyyin Mosque and University. Still operating almost 1,200 years later, Hassani says he hopes the center will remind people that learning is at the core of the Islamic tradition and that the story of the al-Firhi sisters will inspire young Muslim women around the world today.
The word algebra comes from the title of a Persian mathematician's famous 9th century treatise "Kitab al-Jabr Wa l-Mugabala" which translates roughly as "The Book of Reasoning and Balancing." Built on the roots of Greek and Hindu systems, the new algebraic order was a unifying system for rational numbers, irrational numbers and geometrical magnitudes. The same mathematician, Al-Khwarizmi, was also the first to introduce the concept of raising a number to a power.
Many of the most important advances in the study of optics come from the Muslim world," says Hassani. Around the year 1000 Ibn al-Haitham proved that humans see objects by light reflecting off of them and entering the eye, dismissing Euclid and Ptolemy's theories that light was emitted from the eye itself. This great Muslim physicist also discovered the camera obscura phenomenon, which explains how the eye sees images upright due to the connection between the optic nerve and the brain.
According to Hassani, the Prophet Mohammed popularized the use of the first toothbrush in around 600. Using a twig from the Meswak tree, he cleaned his teeth and freshened his breath. Substances similar to Meswak are used in modern toothpaste.
Many of the basics of modern automatics were first put to use in the Muslim world, including the revolutionary crank-connecting rod system. By converting rotary motion to linear motion, the crank enables the lifting of heavy objects with relative ease. This technology, discovered by Al-Jazari in the 12th century, exploded across the globe, leading to everything from the bicycle to the internal combustion engine.
Hospitals as we know them today, with wards and teaching centers, come from 9th century Egypt," explained Hassani. The first such medical center was the Ahmad ibn Tulun Hospital, founded in 872 in Cairo. Tulun hospital provided free care for anyone who needed it -- a policy based on the Muslim tradition of caring for all who are sick. From Cairo, such hospitals spread around the Muslim world.
Now that we are done with that ,let us see some recent inventions by Muslims
Skyscrapers, tallest: The Bangladeshi engineer Fazlur Khan, considered the "Einstein of structural engineering" and "the greatest architectural engineer of the second half of the 20th century" produced designs of structural systems that remain fundamental to all high-rise skyscrapers, which he employed in his constructions for the John Hancock Center and Sears Tower. The Sears Tower remained the world's tallest building up until 2007, when the Burj Dubai, currently under construction in Dubai, surpassed its height as the world's tallest building, reaching 585.7 metres (1,922 ft) in height and will be even taller when complete. The world's tallest twin towers, the Petronas Twin Towers, was also built in Malaysia in 1998.
A variation of the laser harp, this is an electronic musical instrument that plays music without any physical contact, or without even any lasers showing, but the music is played by the musician moving their arms or legs through the air above certain areas of the device. It was invented by martial artistist and musician, Assaf Gurner, who publically presented his invention in 1993. It was also the basis for the Sega Activator, the first full-body motion controller for video games
E-learning micro-lecture: The Khan Academy founded by Bangladeshi American educator Salman Khan in 2006. His online micro-lectures are used by millions of students and teachers around the world.
Real-time anti-fraud system: In 2000, many of the core components of PayPal, including its real-time anti-fraud system, was designed and implemented by Bangladeshi American software engineer Jawed Karim.
Ali shuffle: The "Ali Shuffle" was a boxing move invented by Muhammad Ali, where he moved his feet quickly back and forth to try to confuse his opponent.Rope-a-dope: The rope-a-dope boxing technique was invented by Muhammad Ali during his fight against George Foreman during the "Rumble in the Jungle" in 1974.
Vertically rising ladder: This was invented in Turkey by Murat Nural and won the gold medal at the IENA Invention Fair at Nuremberg in 2007. It was designed to climb high points and facilitate suspending there. The user who inserts his/her feet on the movable climbers moves his/her feet backward and forward and climbs upward on the steps. When the user wants to suspend, he/she fixes the climber on the step. The same procedure is followed reversely while getting down. Thanks to its movable legs, it will be possible to work on it for long time without getting tired, and allows easy operation on rough grounds. It also offers the opportunity to use both hands while on the ladder and easy operation on narrow points. It is also easy to keep and transport thanks to its small body, and there is no need for someone else to hold the ladders while one climbs on higher points on the ladder. It will be easy to carry the materials thanks to its hanger, and due to the fact that its legs on the ground are parallel to the ground it is not buried into the ground, so that it can be used to pick fruits up in the gardens. It also helps the operator to work against the wall when he/she wants to hang something on the wall, and it enables easy operation at angular spaces since the legs on the ground can be curved.
