learn our first spoken language by imitating sounds from our caregivers and anyone or anything in the environment. We even associate names of things to their sounds. So meaning if a child is born deaf‚ he/she will be able to learn to speak or become mute because he/she cannot imitate sounds. Reading comes later after the child masters the ‘look and say’ method of identifying letters and words and begins to read. The child will slowly associate sounds to corresponding texts or letters.

Above all was the sense of hearing. I heard all things in the heaven and in the earth. I heard many things in the underworld. How‚ then‚ am I mad? Observe how healthily -- how calmly I can tell you the whole story. It is impossible to say how first the idea entered my brain. I loved the old man

(TheFreeDictionary.com‚ n.d.) For an ultrasound to work there are events that must happen: in the first event the ultrasound machine transmit high-frequency (1 to 5 megahertz) sound pulses into the body using a probe. The second event sound waves travel into the body and hit a boundary between tissues. The third event some of the sound waves get reflected (is the change in direction of a wave front at an interface between two different media so that the wave front returns into the medium from which it originated

Rumi Night on the Heights/in the Depths of St. Ignacious I am by no means a poetry fanatic. I disliked learning about their structure in middle school into high school. I loathed having to put together haikus and soliloquies for my English class freshman year.
