object Definition and 8 Threads

An object database or object-oriented database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. A third type, object–relational databases, is a hybrid of both approaches.
Object databases have been considered since the early 1980s.

    I Determining whether an object will topple or move without a Slope Test

    I want to determine whether an object will topple or move without a Slope Test. Is there an equation for this? What should I pay attention to when calculating this?

    B Can Earth or any spherical object in space act as a particle collider?

    This is most probably a dumb idea as I'm far from deep physics knowledge but I was thinking. What if Earth is hot inside not because of the pressure and the radioactivity but because it's mass attracts particles (similarly to gravitational lensing) and they collide right in the Earth's center?

    B How to add an object's multiple relativistic speeds from x, y, and z?

    Obviously it'd add up to somewhere between 99% and 100% light speed. So how do you figure that out? In the scenario, you reach 99% light speed in one direction, then without slowing, you start to accelerate into an either directly left or right direction (say the engine can rotate without...

    Seeking Innovative Attachment Solutions for a Biochemistry Project

    I am currently engaged in a local project that requires a unique attachment solution. We need to securely affix a 100g object, coated with cross-linked polyethylene foam, to a board that is covered in synthetic fur. The attachment must be robust enough to endure shaking and bumps. Importantly...

    I How does an object know how far to move when it's moving?

    Space must have properties, it's not just empty nothing, and one of those properties is distance. When an object moves through space at a velocity V information has to be transferred between the object and space. The object has the information that it is moving at velocity V which is...

    I Find the constant acceleration of an object that slows down to a standstill

    Hi all, Let V be an initial velocity, D any distance, and T a time duration. which algorithm allows to obtain a constant acceleration A that make the object to brake from V to a zero speed over D during T? Thanks

    B How is an unstable object balanced?

    The other day I was watching a trials rider balancing a stationary motorcycle and apparently they can do it pretty much indefinitely. I don't understand how they can do it. Say the motorcycle (and rider) starts tipping left. So the rider moves their body to the right to compensate. But this...

    C# Return type that matches type passed to function in C#

    I am working on a project in C# that will be using arrays of various length that need to be determined at runtime. I am attempting to write a small personal library of functions that act on arrays of various types. Right now, I am trying to add an empty element to the end of an array, of...
