Are the brightest stars low magnitude or high magnitude?

The magnitude numbers go opposite to brightness.  

Bright things have low magnitude numbers, and dim things have high magnitude numbers.

-- The dimmest stars a person can see with only his eyes and no optical equipment are around magnitude 6 .

-- Polaris (the 'North Star') is almost exactly magnitude 2 .

-- The full moon is around magnitude -12 .

-- The sun is magnitude -27 .

Each magnitude is a change of 2.154 times, brighter if it's one magnitude lower, or dimmer if it's one magnitude higher.

(I know you're curious to know where that number comes from, but don't ask.  It's another whole story.)

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
