南海的主权存在争议的情况下,中共不惜周边小国的反对自行其事,还显得理直气壮,那么对中国北方大片大片土地沦为俄国的领土有什么勇气、敢对普京提一个字吗?

BBCNews:
Thousands mark summer solstice at Stonehenge

Thousands of people have gathered at Stonehenge to mark this year's summer solstice.
Police said 23,000 attended the neolithic site in Wiltshire to watch the sun rise at 04:52 BST, while others gathered at the nearby Avebury stone circle.
The figure was down on the estimated 36,000 who attended last year and the 30,000 expected this year.
Wiltshire Police said the celebrations were "positive and peaceful".

Manhattanhenge

Sunset looking down 34th Street. One of two days when the sunset is exactly aligned with the grid of streets in Manhattan.

What will future civilizations think of Manhattan Island when they dig it up and find a carefully laid out network of streets and avenues? Surely the grid would be presumed to have astronomical significance, just as we have found for the pre-historic circle of large vertical rocks known as Stonehenge, in the Salisbury Plain of England. For Stonehenge, the special day is the summer solstice, when the Sun rises in perfect alignment with several of the stones, signaling the change of season.

For Manhattan, a place where evening matters more than morning, that special day comes twice a year, when the setting Sun aligns precisely with the Manhattan street grid, creating a radiant glow of light across Manhattan's brick and steel canyons, simultaneously illuminating both the north and south sides of every cross street of the borough's grid. A rare and beautiful sight. These two days happen to correspond with Memorial Day and Baseball's All Star break. Future anthropologists might conclude that, via the Sun, the people who called themselves Americans worshiped War and Baseball.

For these two days, as the Sun sets on the grid, half the disk sits above and half below the horizon. My personal preference for photographs. But the day after also offers Manhattanhenge moments, but at sunset, you instead will find the entire ball of the Sun on the horizon.

Unnoticed by many, the sunset point actually creeps day to day along the horizon: northward until the first day of summer, then returning southward until the first day of winter. In spite of what pop-culture tells you, the Sun rises due east and sets due west only twice per year. On the equinoxes: the first day of spring and of autumn. Every other day, the Sun rises and sets elsewhere on the horizon. Had Manhattan's grid been perfectly aligned with the geographic north-south line, then the days of Manhattanhenge would coincide with the equinoxes. But Manhattan's street grid is rotated 30 degrees east from geographic north, shifting the days of alignment elsewhere into the calendar.

Note that any city crossed by a rectangular grid can identify days where the setting Sun aligns with their streets. But a closer look at such cities around the world shows them to be less than ideal for this purpose. Beyond the grid you need a clear view to the horizon, as Manhattan has across the Hudson River to New Jersey. And tall buildings that line the streets create a vertical channel to frame the setting Sun, creating a striking photographic opportunity.

True, some municipalities have streets named for the Sun, like Sunrise Highway on Long Island and the Sunset Strip in Los Angeles. But these roads are not perfectly straight. And the few times a year when the Sun aligns with one of their stretches of road, all you get is stalled traffic solar glare temporarily blinds drivers.

So Manhattanhenge may just be a unique urban phenomenon in the world, if not the universe.

Note that several years ago, an article in the New York Times identified this annual event as the Manhattan Solstice. But of course, the word solstice translates from the Latin solstitium, meaning stopped sun, in reference to the winter and summer solstices where the Sun's daily arc across the sky reaches its extreme southerly and northerly limits. Manhattanhenge comes about because the Sun's arc has not yet reached these limits, and is on route to them, as we catch a brief glimpse of the setting Sun along the canyons of our narrow streets.

While we are on the subject, when viewed from all latitudes north of the Tropic of Cancer (23.5 degrees north latitude), the Sun always rises at an angle up and to the right, and sets and an angle down and to the right. That's how you can spot a faked sunrise in a movie: it moves up and to the left. Filmmakers are not typically awake in the morning hours to film an actual sunrise, so they film a sunset instead, and then time-reverse it, thinking nobody will notice.

As part of a nationwide campaign to raise awareness of the growing economic espionage threat, the FBI has released a short video, "The Company Man: Protecting America’s Secrets." Based on an actual case, the video illustrates how one company was targeted by foreign actors and what the FBI did to help. More at: https://www.fbi.gov/TheCompanyMan




据英国《金融时报》网站24日报道,FBI官员23日警告称,美国现在每年因贸易机密、知识产权、销售和定价信息以及其他公司数据被窃损失数千亿美元,对美国构成了国家安全威胁。

“中国是我们面临的最主要的经济间谍威胁,”FBI反情报部门助理主任兰德尔·科尔曼表示,“中国政府发挥了重要作用。竞争并不公平。”

FBI在23日推出一项活动,传授企业有关间谍威胁的知识,FBI表示,经济间谍案现在每年高达数百起。

FBI发布了一段视频,名为“公司人:保护美国机密”(The Company Man),并称是“根据真实案例”拍摄,故事大纲如下:

生活焦头烂额的居家男人罗伯特·穆尔为给孩子交大学学费而倍感压力,同时也渴望在公司得到晋升。在这一背景下,两名笨拙的中国企业高官开始接近他,试图收买这家美国公司一流的绝缘技术。他们向穆尔开出20万美元,用以交换他们想要的设计方案。穆尔拒绝了他们并把事情告诉了老板,后者向FBI报告了情况,而FBI则用穆尔设下圈套,抓住了那两人。

美国《外交政策》网站评价,尽管剧本很烂,但是这部电影制作得相当娴熟。

作为FBI广泛计划的一部分,过去一年,这段视频私下向美国企业播放了约1300次。FBI探员敦促企业与FBI合作应对这种威胁。

美国国家情报总监办公室(Office of the Director of National Intelligence)反情报主管威廉·埃文尼纳(William Evanina)表示,在FBI对165家公司的调查中,50%的公司承认,贸易机密或知识产权曾遭窃取,95%的公司怀疑,中国是幕后指使。

有关军事电信、贵金属、混合动力技术、杂交种子和粮食作物、涂料技术以及金融机构数据的信息都是被窃取的目标。

钓鱼手段也被使用,员工点击虚假电邮中的链接,就会中招。电邮中会植入恶意软件或其他有害软件。

今年5月,美国政府指控天津大学(Tianjin University) 3名教授以及另外3位中国公民涉嫌经济间谍活动。美国声称,他们窃取了美国敏感技术,以帮助中国大学和由政府控制的企业。

他们被控从马萨诸塞州的思佳讯(Skyworks Solutions)和科罗拉多州的安华高科技(Avago Technologies)窃取技术信息,该技术应用于智能手机、平板电脑和全球定位系统(GPS)设备,还用于军事。

据陆媒此前报道,应邀至美国凤凰城参加国际微波会议的天津大学教授张浩正是因此在美被捕。

2014年,5名中国军人被控针对美国企业进行网络攻击并涉嫌经济间谍活动。对此,中国外交部发言人秦刚回应,美方对中方人员的指责纯属无中生有,极其荒唐,中方敦促美方立即纠正错误、撤销所谓起诉。秦刚指出,长期以来,美方有关部门对外国政要、企业、个人进行大规模、有组织的网络窃密和监听、监控活动,这已是路人皆知。中国是美方网络窃密和监听、监控的严重受害者。秦刚还宣布,中方决定中止中美网络工作组活动,该工作组是习近平去年夏天访美后,两国为协商黑客问题设立的交流机制。
