The development of the calander shows they can divde the number of minutes hours days month etc in a year. Development of the pyramids shows geometry and engineering. look up to make sure.
The Egyptians developed the 'first calendar' based on the movement of 'star Sirius'.
<u>EXPLANATION:</u>
They applied the principles of astronomy in an effective manner to develop a an almost accurate calendar that was divided into 12 months, 365 days and 24 hours a day. This calendar is still used today.
The pyramids were big structures that were designed using the basis of mathematics and geometry.
The pyramids were built in a specific shape and using correct calculations for dimensions.
This showed that the Egyptians had knowledge of Math and Science and applied these concepts.
Secure all loose gear, hatches or ports. Determine your location and the best course back to shelter. Keep a sharp lookout for the other boats and obstructions.
Changes in the pressure create the flow of the air to move up and down in the ear and thus create popping sound.
Explanation:
The ear-popping is caused by the phenomenon of the opening of the Eustachian tube when one swallows and it might be automatically when you blow our nose or are setting in an airplane and this sound is created when the air enters the middle ear through the tube.
