What is Phenomena: Definition and 166 Discussions

A phenomenon (Greek: φαινόμενον, romanized: phainómenon, lit. 'thing appearing to view'; plural phenomena) is an observable fact or event. The term came into its modern philosophical usage through Immanuel Kant, who contrasted it with the noumenon, which cannot be directly observed. Kant was heavily influenced by Gottfried Wilhelm Leibniz in this part of his philosophy, in which phenomenon and noumenon serve as interrelated technical terms. Far predating this, the ancient Greek Pyrrhonist philosopher Sextus Empiricus also used phenomenon and noumenon as interrelated technical terms.

    Are there other phenomena (besides light) whose speed is invariant?

    Are there any other phenomena (optical or not) whose speed is constant and does not depend on whether the source is moving or not?

    Is There Credible Evidence Supporting Psychic Phenomena?

    If you think there may be something to it all, what you think is the best evidence for psychic phenomena? When I have reviewed various claims of psychic phenomena, one thing that I have noticed is that some skeptics will correctly state that there is no known proof of claims of psychic...

    Struggling to Understand Relativistic Phenomena

    This question has been driving me crazy all night. The question reads: If the speed of light were smaller than it is, would relativistic phenomena be more or less conspicious than they are now? :confused: Honestly, i do not have a clue as to what the question is asking, and without...

    Video Recommendations for Black Holes & other space-related phenomena

    I am currently a student-teacher pursuing my teaching certificate for high school physics. Over the past month or so, my students have been asking a lot about black holes. Since they are showing such an interest in space, I thought it might be a good idea to find a video to show them to...

    Exploring Tunneling to Wave Phenomena

    Hi! I always thought that tunneling was a quantum phenomenum. So another day I found a problem which is about the part of the light that can be transmitted (refracted) even if you send I light beam in an angle greater then the limit angle of two material boundary. By the way looking at a...

    Is consciousness a material phenomena?

    Or does it exist outside the physical universe? This is a little old, but it seems there’s a lot of confusion surrounding this topic. Not only that but it seems consciousness has only been brought back into science since quantum mechanics was introduced. Wasn’t sure where to post this so...

    Your personal experiences of unusual phenomena?

    I am curious to read personal anecdotes any of you may have about physical phenomena that are not seen very often. I don't mean deliberate observations in a laboratory setting. Just something that happened when you were not expecting it. For instance, supposedly the sun as it is setting (or...

    Half-Life Phenomena: Comparing to Hot Coffee

    The book we are using (Physics 101) has shown quit well that there will be a greater quantity of heat loss (and faster), of a substance to it’s environment, if the difference of temperatures between the two is greater. Also, there will be initially a faster rate of heat loss / time...
