科学家鉴定出彩虹中的第八种色彩
 

  据国外媒体报道,光谱中的这种新基本色彩是由兰德尔-门罗大学的物理学家们发现的,当时他们正在探索“慢光”的特性。他们将光子射向超冷钠原子群,两者发生的碰撞使它的速度降低到大约7.6英里每小时。这种慢光随后通过一系列具有特定入射角度的碳纳米管进行汇聚。

  物理学家Flora Padyolis说:“这需要一点横向思维进行理解。你可以将可见光光谱中的每一种色彩与声波中的音律相对应,我们要做的就是以一个全新的角度进行诠释,让人们之前认为的C调听起来像是B调。”

  专家称,这种尚未获名的色彩可以说是自牛顿1671年成功分离白光之后,第一次对传统光谱的增加。

  虽然目前的隐形设计依靠的弯曲物体周围的光线或者隐形于一小部分光谱,科学家提出使用这种色彩有可能带来戏剧性的结果。这种相对简单的新技术也可能为消费者市场带来影响,因为研究人员声称,获得这种色彩成本不会太高。据说时尚界对于这一色彩的发现特别兴奋。

神奇眼镜可判断用户情感

 

网络是内容的消防栓,追踪你喜爱的页面并不容易。英国一群设计系的学生萌发了这样的概念化解决措施:Amoeba,它是一款电子单片眼镜,可以通过监测用户的生物性反馈,将其最感兴趣的页面整理归档。这多像你一直以来都想拥有的情感追踪版谷歌眼镜!

 

Amoeba是由英国皇家艺术学院和伦敦帝国理工学院的学生珊娅、卡琳和弗洛里安设计的,通过3个不同的传感器来监测人的情绪状态。嘴巴附近的热传感器可以监测到呼吸频率,眼镜附近的摄像机可以观察到瞳孔大小,皮肤传感器可以监测到出汗增加。

 

综合分析用户对网页内容的生理反应,或是呼吸急促、出汗增加,或是瞳孔放大,Amoeba就可以判断出其最感兴趣的网址或网页。

 

“我们假设你在浏览网页之前就戴着Amoeba,”珊娅在自己的个人网站上写道,“当你浏览不同网页时,它感应到你的生理状态,并与你的兴趣做匹配。上网结束后,你可以到Amoeba的应用,选择你要查询的关键词。”

 

“这款应用里有你访问的所有链接,按你感兴趣的程度排列,”珊娅解释说,“你也可以选择路径打开特定页面,这更好地反映了你的自主性。”在一个小型测试里,这款设备的模型能以90%的准确率判断出使用者最感兴趣与最没兴趣的文章。

 

这款设备看起来似乎有些古怪,但当我打开38个页面,有些我甚至一眼未看,我就觉得这样的单片眼镜或许是个好注意。

北斗七星由大熊星座七颗明亮的恒星构成,由于它漏斗一样的形状容易被人识别,因此常被用于指示方向。然而,这七颗恒星完全不在同一个平面,我们看到的漏斗形状只是错觉。所见的一切都不尽真实,我们只能在扭曲时空之中寻找那么些所谓的真相。

最权威的期刊上NATURE Physics发表了这篇奇文,描述一个实验物理学家无法自拔地暗恋一名小提琴妹子的悲催故事,可见物理学界的闷骚宅男遍地都是,这篇奇文才能深深触动期刊编辑和审稿人冰冷的心、苛刻的眼光,一路过关斩将、最终发表。

 

Out of sight, out of mind.

 

First off, the obligatory warning. Don’t try this at home, kids! In the hands of inexperienced laymen, the method I am about to describe will inevitably be a disaster. Like, fatal-type disaster. Consider yourself forewarned. That said, I have to admit that Jillian was truly one to die for. I’d never seen a woman whose visage struck me so deeply — smackdab in my gut, and various regions nearby. Whenever I saw her in the flesh, the Mormon Tabernacle Choir would insinuate itself into my brain, and I would reel in response to the ecstasy of her divine musical theme.

Many wise men throughout the ages have written about this sensation. Suffice it for me to say that, if she were a predator and I were her prey, I’d gladly give up my bodily organs for her to
feast upon.


Unfortunately, that was never to be. Jillian didn’t even know I existed. Complete bummer.
And why shouldn’t that be the case? I was an experimental physicist and she a talented concert violinist. We had nothing at all in common between us, aside from the fact that we
both lived in the same apartment building. Furthermore, judging from my surreptitious surveillance of her, she already had an intimate relationship with her orchestra’s bassoon player. Even more of a complete bummer. In the time it would take me to become a competent enough bassoonist to challenge his role, all the protons in the Universe would have disintegrated.

It was a no-win situation. Which is why I began to contemplate suicide.

Trouble was, I didn’t want to die. All I wanted to do was to forget about Jillian, completely and irrevocably. Then I could move on with my life. It was a real dilemma. Just as it is, I’m sure, for a million other sociophobic nerds like me. So here is where it gets a little complicated. Stay with me; don’t sweat the physics stuff. It’s not that hard to follow.

Quantum mechanics boils down to one simple principle: sometimes you win, sometimes you lose and sometimes you get rained out. You can’t be sure of the result until you read about it in the sports section of the newspaper.

But that’s just one interpretation — and there’s every reason to believe it’s the wrong one. We both win and lose. We go on to glory in one version of the Universe, and go down to ignominious defeat in another. (And, not to neglect the other possibility, we get soaking wet in a third.) The field of play is called the multiverse.

But you already knew that, right? Lately, it’s all over TV, movies and the Internet. Few, however, realize that the concept is more than 50 years old. Sometimes it takes that long to agglomerate something into the popular zeitgeist.

It may be difficult to understand how we can exploit this fact to our personal benefit — but that’s what this exposition is all about.

 

How to lose the one you love

Like I said, don’t sweat the small stuff. Bottom line, here’s what you need to kludge together to solve the age-old problem of unrequited love:

1) One big-assed electrical generator, capable of delivering instantaneous jolts of 20 or more amps on demand.

2) Two very large copper cables connected to the positive and negative poles of said generator, terminating in handgrips that you will grasp while standing barefoot in a tub of salt water.

3) A quantum trigger. An old radium-dial watch will do nicely.

4) A photomultiplier tube, to detect the random photons that emanate from the radium source.

5) A video camera, focused on the page of the telephone directory that lists the name of your love interest.

6) A PC programmed to fire off the generator's output when instructed by the quantum trigger, but also to cease firing when the video camera detects the disappearance of said name in the directory.

Simple, right? Remember, you both win and lose. The radium watch dial can either produce a photon within the computer's scanning cycle, or not. Both possibilities are real. The 'you' that survives this process will be the winner, set free, free, free. No more Jillian. No more love dilemma.

True, millions — possibly billions, trillions, quadrillions — of yourselves will die to get there. But they're just bodies under the bridge.

Yet, it's not all so simple. The astute reader will question why and how I can refer to Jillian at all in my tale, when she has never existed in my current Universe.

The answer? I never pulled that quantum trigger. Call me a hopeless romantic, but I just couldn't envisage living in a Universe where I didn't love Jillian.
