Muslim/Arab Inventions Or European/American inventions. Who made more?
in General

I will try to present both sides, As unbiased as i can. 
Islam / Arab World :

Another 5 more. [5 are invalid, As they were in the other link]
24 so far. 25 now, When we include Hotmail. 
Carpets
Carpets were regarded as part of Paradise by medieval Muslims, thanks to their advanced weaving techniques, new tinctures from Islamic chemistry and highly developed sense of pattern and arabesque which were the basis of Islam’s non-representational art. In contrast, Europe’s floors were distinctly earthly, not to say earthy, until Arabian and Persian carpets were introduced. In England, as Erasmus recorded, floors were “covered in rushes, occasionally renewed, but so imperfectly that the bottom layer is left undisturbed, sometimes for 20 years, harbouring expectoration, vomiting, the leakage of dogs and men, ale droppings, scraps of fish, and other abominations not fit to be mentioned”. Carpets, unsurprisingly, caught on quickly.

Blood Circulation and Anatomy

While Westerners credit William Harvey for discovering blood circulation in 1616, pulmonary circulation had already been described by the Arabic doctor Ibn Al-Nafis 300 years before. While his knowledge was incomplete, Al-Nafis knew that the heart had two halves and that blood passed through the lungs when traveling from one side of the heart to the other. He also realized that the heart is nourished by capillaries.

Pharmacies

Islamic pharmacies, called saydalas, began at the same time as the hospitals, in the late 700s, as part of the Islamic health care system. While Western apothecaries sold ground mummies, dried dung and other strange substances as well as herbs and spices, Muslim pharmacists focused on empiricism—they used substances that showed a positive effect on the patients. In other words, if an herb, spice or other ingredient worked by assisting a sick person to heal, it was used. As Islamic pharmacology evolved, the great Muslim doctors like Al Razi, Avicenna and Al kindi discovered many healing substances for their pharmacies.

Arab pharmacies were government-supervised to ensure the purity and overall quality of the medications, which were weighed in verified scales and labeled correctly. Pharmacies began to spread throughout the Muslim world during the 9th century onwards, whether connected to a hospital or standing alone. Al-Nifas, besides his work on the circulation system, also developed a system of dosage for medications using mathematics.

As Islamic medical knowledge and methods began to filter into Western medieval medicine during the 12th century, so did their treatments for specific diseases. New healing substances were added to Western apothecaries while certain Western medicines, such as theriac, moved into Arab countries due to the growing Arab-European trade.

There might be more.  Seeing as how Arabs and Muslims were pretty much the same. As all muslims who discovered things, Were arabs. So i haven't even counted the christian arabs.
Now for the american and european inventions [Which is a bit unfair, Considering i only counted islamic inventions. And not arabs as a whole]

Around 40-42 , In which some are chips, And ice pops, Which is quite laughable.

https://europeisnotdead.com/video/broadcasts-of-europe/european-inventions/
Around 35-38 In total the european and americans have:  76-78
While muslim arabs ALONE have 51.
I'll continue tomorrow.
