People do it all the time. It only takes a grim determination to force yourself consciously to interact with each new wave of technology, no matter how insipid it seems.
这种事其实人们都在做，成败的关键只在于你是否有意识地狠下决心强迫自己与科技的每次新浪潮互动，不管它看起来有多乏味无聊。
The most famous duality in physics is the wave-particle duality. This one states that matter has both wave-like and particle-like properties.
在物理学上最著名的二元性例子就是波粒二象性，这表明物同时具有波和粒两种属性。
Changing the world's energy and agricultural systems is no small matter. It is not enough to just wave our hands and declare that climate change is an emergency.
改变世界能源和农业系统绝不是小问题，仅仅挥手宣布气候变化是紧急情况是不够的。
The 'wave' properties of macroscopic matter are not apparent because the wavelength is undetectably small.
宏观物质的波动特性不明显，因为其波长很短，难以被察觉。
A new interpretation for the energy exchanges of the matter system is given when there exists the gravitational wave.
对物质体系在发射和接收引力波时的能量转换作了新解释。
No matter from the wave type structure, space, time, speed, all the signs are that, large periodic wave two adjustment will end.
无论从浪型结构、空间、时间、速度，这一切的迹象都表明，大周期二浪调整将结束。
No matter what polarization of the incident electromagnetic wave, element's transmission characteristics for the regular triangle arrangement is more stable than that of square arrangement.
但无论入射波是什么极化方式，所设计单元按正三角形布阵时的传输特性都比正方形布阵方式稳定。
But let's just try maybe one of the basic questions they could ask, and they can say, all right, DE Broglie, so you say that all matter, absolutely all matter has wave-like behavior.
让我们试一试他们，可能问到的一个基础问题，他们会说，好的，德布罗意，你说所有的物质，所有物质绝对会有波的特性。
But even then, matter at very small scales has a spread out wave-like nature, which means you can't have both the pencil perfectly upright and not moving at the same time.
即使这样十分微小的物质具有类似于波的本质，也就是说铅笔完全竖直与保持平衡不动，不可同时兼得。
