Once you run out of ammo you bite the top off that fat lead acid battery and fling it in their trench.
It is amazing how much lighting has improved just during my lifetime, let alone since WWII. The best commonly available flashlight you could buy when I was a kid was a D cell maglight, with an incandescent bulb. Those were considered very bright back then. Compare one now to even a cheapo $5 LED flashlight from Walmart and there isn't even a competition in lumens output. Sure, the maglight is still better made and has other features that make it nice, but the output from lights and their relative size has improved 1000% from when I was a kid. In my 20's my friend had this massive pistol grip flashlight for off-roading that plugged into his cigarette lighter. The thing must have weighed 5 pounds. I have a little Rovyvon flashlight on my keychain now that weighs less than an ounce and it puts out more light than that pistol grip light did back then. Progress, baby!
LEDs really made that jump possible. Any other alternatives to incandescent were either bulky, fragile or power hungry.
If you really want to see something cool, watch the history of how blue LEDs were invented which was the ultimate game changer.
Wow! That was beyond interesting, that was amazing. I even see a lot of parallels between Nakamura's journey to becoming a full-fledged engineer, respected by his peers, and my journey towards becoming a full-fledged website engineer. It does take massive amounts of determination, creativity, and ignoring all of the nay sayers. Nakamura is an amazing person.
The new CEO of Nichia sounds like a horrible person. Petty and vindictive, greedy, and entitled. Personifying the characteristics we often see from people born into wealth and position. Not only did he lack vision, creativity, and adventure, he actively tried to block all of the progress that Nakamura was making, and then stole all the money, and attempted to steal all the credit after Nakamura had his breakthroughs.
I was so happy to hear that Nakamura won the Nobel prize. That at long last would have provided him with some financial compensation for all of his hard work and genius. I was also very happy to hear how widely published he is, and that he was able to retain all of the reputational credit for his accomplishments.
I have a passing familiarity with LEDs because of my electronics tinkering hobbies, but I didn't realize just how much material science, physics, and chemistry was involved in their invention and manufacturing. Thank you so much for sharing such an awesome video with me! I just shared it with my son and a few close friends who I know will enjoy it.

Rules:
1) Treat Others in a Civil Manner. This is not the place to deride others for their race, sexuality, or etc. Personal insults of other members are not welcome here. Neither are calls for violence.
2) No Contemporary Politics Historical politics that influenced designs or adoption of designs are excluded from this rule. Acknowledgement of existing laws to explain designs is also permissable, so long as comments aren't in made to advocate or oppose a policy. Let's not make this a place where we battle over which color ties our politicians should have, or the issues of today.
3) No Advertising This doesn't apply to posting historical advertisements.
4) Keep Post on Topic This rule will be enforced with leeway. Just keep it related to arms or Forgotten Weapons. If you feel you have something that's worth posting here that isn't about either of those (and doesn't violate other rules) feel free to reach out to a mod.
5) No NSFW Content Please refrain from posting uncensored extreme gore or sexualized content. If censored these posts may be fine.
Post Guide Lines
These are suggestions not rules.
-Provide a duration for videos. eg. [12:34]
-Provide a year to either indicate when a specific design was produced, patented, or released. If you have an older design being used in a recent conflict provide the year the picture was taken. Dates should be included to help contextualize, not necessarily give exact periods.
-Post a full URL, on mobile devices it can be hard to tell what you're clicking on if you only see "(Link)".
-Posts do not have to be just firearms. Blades, bows, etc. are also welcome.
