@sanguibee 十多年前的德国队是世界杯足球史唯一能和阿根廷在点球大战一较高下的，落花随流水而去，被污染的DNA修复不了啦

@Pathusa 看前面一段描述就觉得是肾结石，因为我曾经受过类似痛楚总以为是肠胃问题持续一个多星期

@Pathusa 推主经常晨勃？难得还能保持好色之心

@sanguibee 桂哥你太多心了，老马若能以教练身份拿一次大力神，他地位只会更超然更难超越

@HeQinglian 川普年纪越大越是冲动型决策，太可怕。

@HeQinglian 四年庸君，二年昏君。还有二年，战战兢兢。

7 materials that sound like science fiction, but are real and in use right now:

1. Aerogel
97% air. Lightest solid material ever created. Used in Mars rovers. Looks like frozen smoke.

2. Metallic glass
Metal with the atomic structure of glass, no crystal grain boundaries. Harder than steel, more elastic than titanium. Used in phone glass and surgical tools.

3. Quantum dots
Nanocrystals that glow different colors based purely on their size, not their chemical composition. In your TV screen right now.

4. Graphene
One atom thick. 200x stronger than steel. Conducts electricity better than copper. Still being scaled up for mass production.

5. Self-healing polymers
Plastics that repair their own cracks when exposed to heat or UV light. In prototype aircraft skins and phone cases.

6. D3O
Flows like liquid, hardens on impact. Used in military helmets and phone cases. No rigid structure, until it needs to be rigid.

7. Transparent aluminium (ALON)
Literally transparent aluminum. Harder than glass, used in military aircraft windows and armor. First theorized in Star Trek. Then actually made.

@sanguibee 中国应盘算如何让国际婚介多输送乌克兰妞进来結婚交配提升人口素质也解決了乌克兰单身女性泛滥问题

[Com$Dem @ComDem2]

@Pathusa 推主跟吗？

[Com$Dem @ComDem2]

@Pathusa 靠，什么州这么便宜

[Com$Dem @ComDem2]

@sanguibee 就让加州倾底变烂，反正那群科技公司大不了搬去其他州，免得那帮左傻子老是叫春般喊加州是第三经济体，就让他们做个共产榜样给全世界看看也好
