what is meant by 'science explains'?


"When we say ‘science explains’ something we usually mean that there exists a scientific description of the phenomenon in question. Thus the force of gravity — rather important since it keeps us from bumping around on the ceiling like helium balloons — can be expressed by a simple mathematical formula. The formula equates the gravitational force between two objects to the product of their masses multiplied by a universal constant (the ‘gravitational constant’) and divided by the square of the distance between them. But does the equation ‘explain’ why you don’t bump your head on the ceiling? Not really. It tells us there is a force that keeps your feet on the ground, but you knew that already. It also quantifies that force, allowing us to calculate its strength in any particular case, which is extremely useful. But it doesn't tell us why there is such a force, why it follows an inverse square law, and why the ‘gravitational constant’ has the value that it does. The equation is a description of gravity rather than an explanation."

bible reading dec 3-5

  Bible reading for weekend December 3 -- 5  Dec 3 -- Nahum 1 and Luke 17 Dec 4 -- Nahum 2 and Luke 18 Dec 5 -- Nahum 3 and Luke 19 ================ "The LORD is good, a stronghold in the day of trouble; he knows those who take refuge in him. But with an overflowing flood he will make a complete end of the adversaries, and will pursue his enemies into darkness." (Nahum 1:7-8)  TIME'S UP FOR NINEVEH (Nah 1-3). The prophecy of Nahum is God's word to the people of Nineveh, part two. Jonah was part one, chronicling a city-wide repentance of Assyrians in the capital about a hundred years earlier. The closing bookend is Nahum, and the Assyrian empire is big, powerful, and aggressive. Notice the references to chariots (2:3-4, 13; 3:2). The Assyrians were a militarily advanced culture, and cruel in their warfare. Whatever spiritual receptivity they had at the time of Jonah was gone by the time of Nahum. Nahum may not have actually visited Nineveh, for it seems the book was w

bible reading nov 1-2

  Bible reading for weekend Nov 1 -- 2 Nov 1 -- Hosea 7 and Psalms 120-122 Nov 2 -- Hosea 8 and Psalms 123-125 ================   "Were I to write for him my laws by the ten thousands, they would be regarded as a strange thing." (Hosea 8:12) THE RESULTS OF SIN (ch 7-8). Notice the words and metaphors to describe Israel's sinful condition: they are surrounded with, and proud of, their evil (7:1-3); like adulterers in the heat of passion (7:4-5); their anger is like a hot oven (7:6-7); they are like a half-cooked (one side only) cake (7:8); their strength is gone (7:9); they are like silly doves easily trapped (7:11-12); they are undependable like a warped bow (7:16). In spite of all of this they are so proud of themselves! (We might say they have a strong self-esteem.) They have spurned what is good (8:3); they sow to the wind and have no real fruit (8:7); they are a useless vessel (8:8) and a wild donkey wandering alone (8:9); they regard God's law as a strange thing

Howard Hendricks on OT books chronology

When I was in seminary, Howard Hendricks (aka "Prof") gave us a little card with the books of the OT chronologically arranged. The scanned copy I have was a bit blurry and I wanted to make something like this available for our church class in OT theology ("Story of Redemption"). A few minor edits and here it is...
