Because of the basic rule of the scientific process. A scientist's findings must be repeatable by others in similar conditions to dispel any belief that results were not due to the scientist's error, fancy, motives, etc.
the all time time one don't run when using machinery always where goggles always look what you ae doing and where you are going always have a penical
plastic invented by Alexander Parkes for the first time.
Unfortunately, no, but it would be cool. We can't do anything apart from wait.
| --- add (enqueue) ---> ... | --- remove (dequeue) ---> |By definition, First-in-First-out is the primary characteristic of being a queue. For any given time, the position of adding an item, or enqueue, is always from the left (directions shown as above, but they are just abstraction), and deleting one, or dequeue, is always from the right. The derived property or attribute of a queue is the adding position is always >= deleting positionWhen the positions of these 2 fundamental operations are at the same position, the queue is EMPTY. And we know there is no way to be less than EMPTY of a queue, right?! Thus, insertion and deletion positions of the queue are NEVER interchanged.If they could be interchanged, then the thing you have is just a container, not a specialized container to fulfill First-IN-First-OUT (QUEUE). (the ones in the container are not served as the order they came in)
Invent.
The team of scientists that worked for the first time on the research of the Hydrogen Bomb would be the Aldermaston scientists. Sir William Penney was in charge of the project.
Humans
nobody knows, dinosaur skin color has always been a mystery to scientists
No
Scientists have always reached their conclusions by means of observation and reasoning, whether in the middle ages or at any other time.
They think in the messianic period
always, and the second time as well
Scientists first developed the geologic time scale by studying rock layers and index fossils worldwide. With this info. (information if you forget!), scientists placed Earth's rocks in order by the relative age.
First.
Scientists believe it was in about 3500 BC (about 5500 years ago).
long time ago....always back in the B.C time!!!!
Two main reasons. First, to make sure that the scientists who came up with a new idea didn't just "get lucky" in their laboratory and that the experiment is repeatable. Second, science is always progressing. So the way that we view something can be changed in the future, most likely by an advancement in technology.
