I am trying to write a little paragragh on RS, the subject and I need to write about the many siginificant discoveries that have been really helpfyul in the past 100 years or in recent years.

I just need some ideas.

A great many discoveries have a religious or ethical side(s) to them.

Lets take advances in DNA testing as an example. This has led to 'DNA finger printing'. An ethical question might be 'Should there be a DNA finger print data base? On religious grounds you might object to being sampled for DNA testing.
More wider DNA testing has demonstated that man has been around much longer than the 6500 years the bible suggests. Some DNA tesing results conflict with some other religion views (e.g. Mormon - (Broken Link Removed)

There are many other discoveries you could use. Here are a few, but you will have to think up the religious or ethical questions. Remember to think of the religiious questions from other than the Christian view as well.

Carbon-14 radiodating
penicillin
IVF
genetic modification of crops

Another discovery: body part replacement: heart, lungs, eyes, liver, arteries, veins, all these caused some turmoil for religious or ethical thinkers.

Finally, transportation has had a great impact on society: residence, work place, work habits,dating habits.

And one other discovery: The birth control pill. That has had a major impact on the lives of many people, and religious have grappled with it because it allows women to be free of dependence on men. Many, many religions depend on women to be inferior and subservient to men as a basic tenet of control in the church.

To find significant discoveries in the field of RS (which I assume refers to the subject of your paragraph), you can follow these steps:

1. Start by determining the scope of your search: Do you want to focus on RS discoveries in the past 100 years or specifically in recent years? Clarifying this will help narrow down your options.

2. Conduct preliminary research: Use academic search engines (such as Google Scholar or PubMed), scientific journals, or reputable websites to identify key discoveries in RS. Keywords you can use while searching may include "RS discoveries," "significant advancements in RS," or "RS breakthroughs."

3. Look for scientific milestones: Seek out major breakthroughs or revolutionary discoveries that have made a significant impact on the field of RS. Examples could be the discovery of radio waves by James Clerk Maxwell, the development of the laser, or the invention of MRI technology.

4. Explore recent developments: If you are focusing on recent years, consider looking for recent discoveries and advancements that have shaped RS. For instance, you could explore topics like quantum computing, artificial intelligence in RS, or advancements in imaging techniques.

5. Organize your findings: Once you have a list of potential discoveries, categorize them based on their impact. You may also want to consider the specific areas of RS these discoveries relate to, such as imaging, communication, or signal processing.

Remember to cite your sources appropriately when discussing each discovery in your paragraph. Additionally, consider discussing the practical applications, implications, and future potential of these discoveries in the field of RS.
