SPEEDING CLOCK OR CALCULATING CLOCK
In 1623 and 1624, reported his design and construction of what he referred to as an arithmetical instrument that he has invented but which would later be described as a (calculating clock). The machine was designed to assist in all the four basic functions of arithmetic (addition, subtraction, multiplication and division). Amongst its uses, Schickard suggested it would help in the laborious task of calculating astronomical tables. The machine could add and subtract six-digit numbers, and indicated an overflow of this capacity by ringing a bell. The adding machine in the base was primarily provided to assist in the difficult task of adding or multiplying two multi-digit numbers. To this end an ingenious arrangement of rotatable Napier's bones were mounted on it. It even had an additional "memory register" to record intermediate calculations. Schickard’s machine was not programmable.

WHAT DO YOU THINK? - We have all sinned and deserve God's judgment. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him. Jesus, the creator and eternal Son of God, who lived a sinless life, loves us so much that He died for our sins, taking the punishment that we deserve, was buried, and rose from the dead according to the Bible. If you truly believe and trust this in your heart, receiving Jesus alone as your Savior, declaring, "Jesus is Lord," you will be saved from judgement, and spend eternity with God in heaven.
What is your response?
Yes, today, I'm deciding to follow Jesus
Yes, I'm already the follower of Jesus.
