Next today, gas prices, they are free falling, and it looks like they are only going to get lower.The U.S. national average for a gallon of gas was 3.26 one year ago. It's about 2.67 now. By next spring, analysts predict it will be below two bucks a gallon. Why?U.S. oil production, for one thing, it's booming. Even though a method called hydraulic fracturing or fracking is controversial, it's yielding a lot of oil.Also, the price of crude oil, the biggest factor in the price of gas, it's dropping.There's less demand for crude in Asia and Europe where economies have slowed down.All this is good for us, drivers, it's not for countries whose economies depend largely on crude oil sales.The Smithsonian Institution, the largest museum complex in the world, has a new way for you to wrap your mind and your hands around history.It's using three-dimensional imaging to scan everything from Abraham Lincoln's facial structure to a T-Rex toe.And if you have access to a 3-D printer, you can use it to create replicas of priceless and matchless museum artifacts.It's a-look at the crass commercialization part of this, but we are a few years away from like really, really good Halloween costumes.It's up and coming. Yeah.How long does the president have to sit for this?It took from the minute he walked into the room until we were done with the process seven minutes.
接下来我们关注正在下跌的天然气价格,看起来价格会一周持续走低。去年美国全国平均每加仑汽油是3.26美元。现在则是2.67美元。而分析师预计明年春天将跌破2美元。原因何在?首先美国的石油生产正在蓬勃发展。即使名为水力压裂技术或液压破裂法的新技术存在争议,但仍然能够产生大量石油。同时天然气价格最关键因素的原油价格却呈现下降趋势。亚洲对于原油的需求量降低而以及欧洲经济放缓。而这一切都对我们的司机们有利,各个国家的经济在很大程度上已经不再依赖原油销售。世界上最大的博物馆联合机构史密森学会正应用一种新方法将你的意识思想及你的手接触了解历史。这家博物馆正应用三维成像技术扫描从亚伯拉罕・林肯的面部结构到霸王龙的脚趾的一切收藏。如果你能够使用3D打印机,你就可以创造这间博物馆中价值连城且独一无二工艺品的复制品。看看这件粗糙的商业文明时期的工艺品,但是几年前我们真的认为这是件非常好的万圣节服装。这是触摸未来。是的。总统要坐多久?从他走进房间那一刻,直到我们用7分钟完成为止。
