You are wrong. No Innovations at all. Just reusage of allready invented stuff, nothing more. I mean really new stuff in science.
For example motorcycles, you were mentioning: electronics were invented by white ppl, internal combustion engine were invented by white ppl.
All modern stuff were discovered/invented by white ppl. WTF even wheel's were invented by white ppl.
Radioctivity were discovered by white ppl (Marie Curie, Henri Becquerel); nucklear fussion were discovered by white man (Otto Hahn).
What else ?
For starters, the Japanese are linked with countless innovations, such as: Wireless transmission, Flat panel displays, Bullet trains, Flash memory, Blue laser, Compact Discs, Blu-ray Discs, Android (robots), Motion-sensing controllers, Pocket calculators, General anesthesia, the Digital Camera just to name a few.
And secondly, who cares who invented all that stuff, the fact is who has utilised it the best. And the Japanese are far superior when making high quality products than most of Europe , China and America. This is common knowledge.
Richard Lynn’s books “IQ and the Wealth of Nations” and “Race Differences in Intelligence" based on Worldwide Cultural IQ comparisons sees the Japanese come in 5th with an an above average score of 105. The top 5 are all from the East Asian Countries. Moving over to Europe, the UK scores 100, Germany is just behind on 99 along with several countries like Finland. The US is just behind on 98. Only a fool would think the Japanese are fools.
Not only this, the reactor at Fukushima was American designed and made and the Americans decided how close to the water the reactor should be. The plant comprises six separate boiling water reactors originally designed by General Electric. In 1971, General Electric designed, built and delivered the first, now-exploded, Mark 1 reactor at the Fukushima Daiichi nuclear plant and that design was also used for four of the other five reactors.
Also,there was a Whistleblower by the name of Dale Bridenbaugh, a former engineer for GE, he exposed a critical flaw in the reactor design that was so bad, he recommended all Mark 1 reactors be shut down to repair them. This didn't happen. God Bless Americans love of putting profit over other peoples welfare.
