1
00:00:00,160 --> 00:00:02,440
Speaker 1: It's not every day you get to rewrite ancient history,

2
00:00:02,480 --> 00:00:05,240
Speaker 1: but MIT Professor admir Message is doing that.

3
00:00:05,440 --> 00:00:11,879
Speaker 2: Ancient scholars dates write about magic powder that reacts differently

4
00:00:11,920 --> 00:00:13,760
Speaker 2: with the lime and water.

5
00:00:14,040 --> 00:00:17,599
Speaker 1: He's a modern materials chemist who's discovering the exact ingredients

6
00:00:17,600 --> 00:00:20,800
Speaker 1: and process of making Roman concrete with the help of archaeologists.

7
00:00:20,800 --> 00:00:24,160
Speaker 1: He's just published evidence that the ancient engineer Vitruvius got

8
00:00:24,160 --> 00:00:27,280
Speaker 1: the process wrong. Roman concrete has the incredible property of

9
00:00:27,280 --> 00:00:28,680
Speaker 1: being able to fix itself.

10
00:00:28,720 --> 00:00:33,240
Speaker 2: When the microcrack is formed in an ancient Roman concrete,

11
00:00:33,640 --> 00:00:35,720
Speaker 2: this crack will be healed.

12
00:00:35,920 --> 00:00:38,560
Speaker 1: The professor is trying to isolate the self healing element

13
00:00:38,640 --> 00:00:41,400
Speaker 1: in the concrete for use in our own buildings now, and.

14
00:00:41,400 --> 00:00:45,280
Speaker 2: If we are able to make everything lost instead of

15
00:00:45,280 --> 00:00:47,559
Speaker 2: one hundred years one hundred and fifty years, that will

16
00:00:47,640 --> 00:00:49,360
Speaker 2: translate into a huge impact.
