新西兰环卡托大学物理论文代写:原子和分子

布朗运动是由于它们与其他原子或分子碰撞而在流体中随机运动的流体。布朗运动也被称为pedesis,它来自希腊语中的“跳跃”。尽管与周围介质中的原子和分子的大小相比,粒子可能很大,但是它可以通过许多微小的快速移动的质量来移动。布朗运动可以被认为是受许多微观随机效应影响的粒子的宏观(可见)图像。布朗运动的名字来自苏格兰植物学家罗伯特布朗,后者观察到花粉粒在水中随机移动。他在1827年描述了这一动议,但无法解释。虽然pedesis的名字来自布朗,但他并不是第一个描述它的人。罗马诗人Lucretius描述了公元前60年左右尘埃粒子的运动,他将其用作原子的证据。直到1905年阿尔伯特·爱因斯坦发表了一篇论文,解释了花粉被液体中的水分子移动时,这种运输现象仍未得到解释。与Lucretius一样,爱因斯坦的解释充当了原子和分子存在的间接证据。请记住,在20世纪之交,这种微小物质单元的存在只是理论问题。 1908年,让·佩林(Jean Perrin)通过实验证实了爱因斯坦的假设,这一假设为佩林赢得了1926年的诺贝尔物理学奖“因为他对物质的不连续结构的研究”。 新西兰环卡托大学物理论文代写:原子和分子 Brownian motion is a fluid that moves randomly in a fluid due to collisions with other atoms or molecules. The Brownian movement, also known as pedesis, comes from the Greek "jump". Although the particles may be large compared to the size of the atoms and molecules in the surrounding medium, they can be moved by many tiny fast moving masses. Brownian motion can be thought of as a macroscopic (visible) image of a particle that is affected by many microscopic random effects. The Brown movement's name comes from the Scottish botanist Robert Brown, who observed that pollen grains move randomly in the water. He described the motion in 1827 but could not explain it. Although pedesis' name comes from Brown, he is not the first to describe it. The Roman poet Lucretius described the movement of dust particles around 60 BC, which he used as evidence of the atom. It was not until 1905 that Albert Einstein published...
