思想实验：在卧室测量地球的周长
我想通过从我的卧室窗户向外看，来测量地球的周长，而不需要向任何人寻求帮助。<p>尽管我尝试了很多次，但我无法在没有先测量距离的情况下得出周长。如果情况并非如此，请告诉我。<p>如果无法明确知道测量的周长，但我可以知道一些诸如轨道角度之类的值，我发现周长的现实相对于我处于一种叠加状态，对我来说没有实际意义。<p>如果我没有使用科学进行测量，我就不在经典现实中存在，而是在量子现实中存在。如何在没有得出任何数字（例如，太忙于玩电脑游戏）的情况下量化相对论对我的适用性？显然它是适用的，但这些量并没有被测量。<p>如果我不在经典现实中存在，因为我从未测量过任何东西，我不必接受了解周围系统的所有信息会导致确定性结果的观点，我可以有信心认为预定结果并不适用。潜在的确定性结果是由我决定进行测量而决定的。<p>通过我尝试从卧室测量地球周长的经历，我得出结论：经典物理是科学（测量）的结果，而不是关于现实的基本真理。我确定，通过测量而固定的结果是我决定进行测量的结果，因此我得出我拥有自由意志的结论。

I want to measure the circumference of the Earth by looking out of my bedroom window without having to ask for anyones help.<p>As much as I have tried, I cannot realise the circumference without first measuring a distance. Please tell me if this is not the case somehow.<p>If it is not possible to know the explicit measured circumference, but I can know values such as orbital angles, I find that the reality of the circumference is in a superposition relative to myself, it has no actual meaning to me.<p>Without having used science to make measurements, I do not exist in a classical reality, I exist in a quantum one. How can I quantify how relativity applies to me without having derived any numbers (e.g. too busy playing computer games). Clearly it does apply, but the quantities are not measured.<p>If I do not exist in a classical reality because I never measured anything, I do not have to accept that knowing everything about the system around me results in a deterministic outcome, I can have confidence that a predetermined outcome does not apply. Potentially deterministic outcomes are decided by my decision to make measurements.<p>From my attempt to measure the circumference of the Earth from my bedroom I have concluded that Classical Physics is the result of Science (measurements) and not a fundamental truth about reality. I have determined that the outcome that becomes fixed via measurement is the result of my decision to make a measurement and from this I determine that I have free will.
