What is the difference between MDF and particleboard?

MDF uses a finer particle than particleboard. The result is a board that machines better ( more evenly) and has a nicer finish surface whereas particle board is used more in underlayment situations where the board will be hidden.

Is it precisely true that gauss' law states that the total no. of lines of force crossing any closed surface in the outward direction is proportional to net positive charge enclosed within the surface?

As soon as you ask "Is it precisely true ...", we know immediately that it must not be, and we know that our task is to search your version of the statement for the hidden gotchas. I don't think Gauss stated his "Law of Electricity" in terms of 'lines of force'. Seems to me more likely that he stated it in terms of the surface integral over the closed surface. But even if you want to state it in terms of 'lines', then there are a couple of small problems with the way it's stated in the question above: 1). Instead of the "total" number of lines, it would have to be the "net" number of lines, and it would have to say something about the lines crossing the closed surface in the direction normal to it, in case the closed surface isn't a sphere. 2). Gauss talked about just plain charge, without regard for positive or negative as quoted here. And corresponding to that item, he wouldn't have mentioned the "outward direction" either.


What is the difference between discoverable and visible?

discoverable means you can "find" something even if it is not readily visible, and visible means you see something that is very apparent. So its a big difference between the two. As an example: The gas held within Marcellus Shale in Pennsylvania is not visible, and was not discoverable until someone hypothesized that certain rock layers might hold reserves of natural gas. The presence of the gas is not visible in any context; the only proof it exists is when natural gas comes to the surface via pipes after the rocks are fractured using specialized new technology called 'fracking'. Similarly in the 1800s, oil under the earth's surface was not visible and its only presence seen by the naked eye were random pools of oil which Native American Indians used by scraping off the top of the small pools. At one time, this petroleum oil was used to treat a variety of medical conditions. But no one had the ability to extract the oil from under the surface until men used the basics of water-well drilling to design the first oil derrick drill (see Drake's Oil Derrick in Pennsylvania). Once men began drilling and hit an oil pocket, it was carried to the surface via pipes and collected, at which point the oil was visible and measurable. Electrical current was visible to inventors, primarily through lightning. But the process to make an electric light had to go through a discovery process -- discoverable-- before citizens could benefit from the electric light/bulb. But, even now, the various components that make electricity work are largely invisible to everyday citizens-- only things like electrical cords, electrical outlets, lamps, and bulbs are visible, but what makes each work is mostly hidden from direct viewing. In Law, 'discovery' relates to sharing known evidence. Evidence may be something visible-- a murder weapon, for example-- while other evidence may or may not be discoverable--for example, the motive behind a murder. The bridge between what is visible (known, seen) and what is discoverable (unknown, unseen) is often an "hypothesis". Whether it's a Prosecuting Attorney trying to build a logical case, or a scientist trying to prove a logical outcome, both use hypothesis (thinking about and choosing a specific idea) to try to make something discoverable and / or visible. For example, a Prosecuting Attorney knows that phone records can often prove a suspect's prior where aouts; he hypothesizes that he can prove a defendant is guilty by reviewing the phone records. Einstein hypothesized over many ideas that ended up being his inventions.
