Is anyone lost in space?
Is anyone lost in space? A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA’s space shuttle. What are the risks of […]
Does the direction of EMF depend on direction of current?
Does the direction of EMF depend on direction of current? Direction of EMF is decided by the construction of the battery cell, it does not depend upon the direction of the current flow. In fact direction of the current flow depends upon the direction of emf. However direction of the voltage drop depends upon the […]
Does drag force increase as velocity increases?
Does drag force increase as velocity increases? The downward force of gravity remains constant regardless of the velocity at which the person is moving. However, as the person’s velocity increases, the magnitude of the drag force increases until the magnitude of the drag force is equal to the gravitational force, thus producing a net force […]
Can you feel when your brain is touched?
Can you feel when your brain is touched? How much you empathize with other people seems to reflect how strongly your brain—your primary somatosensory cortex—“feels with” them when you see them being touched. Of course, all these claims require further investigation. And, of course, empathy is a complex phenomenon. Does the brain touch the skull? […]
What are the 3 layers of arteries?
What are the 3 layers of arteries? The artery wall is comprised of three distinct layers: the intima, media, and adventitia. The intima is the innermost of three concentric layers, and is mainly connective tissue composed of a continuous ECs monolayer directly attached to the basement membrane which consists of collagen type IV and elastin. […]

What is the purpose of a spectrograph?
What is the purpose of a spectrograph? A spectrograph is an instrument that separates incoming light by its wavelength or frequency and records the resulting spectrum in some kind of multichannel detector, like a photographic plate. Many astronomical observations use telescopes as, essentially, spectrographs. What are spectral features of an image? Spectral features of images, […]
