Here are some of my favorite Stunning Scientific Miracles in the Glorious Quran from among the tens (10s) that are listed in the main sections, below:

1-  Here is one stunning Numerical Miracle, from the 10s below, for you:

The Glorious Quran has 114 Chapters. The sum of those Chapters is 6555 (1+2+...+114 = 6555). There are also 6236 Noble Verses in the Glorious Quran. Now, IF YOU ADD EACH CHAPTER # with the number of its Verses, then you get a list of numbers. So 1 (first Chapter) + 7 (# of its Verses) = 8. Do this for all Chapters.

1-  The sum of the odd numbers from the list = 6555.
2-  The sum of the even numbers from the list = 6236.

See the XLS file for 100% confirmation.
  

2-  The Great Miracle.  Allah Almighty in the Holy Quran called the Number 19 Miracle "One of the Mighty Ones (Miracles)" (74:30-37) [1] [2].  See the 100s of Noble Verses that clearly testify to this Great Miracle.  Also, did you know that Allah Almighty Said in Surat Nuh (that's Noble Chapter Nuh (Noah)) that Prophet Noah lived for 950 years among his people. 

Yet, all Praise and Glory are due to Allah Almighty Alone, the entire Noble Surah is exactly written in 950 Letters [1] [2]!  You can thoroughly see this in the scanned images that thoroughly verify every single Noble Letter, in the links.  Click on the links to see the many other Numerical Miracles in the Holy Quran.  Also, see the Numerical Miracles section along with all of the other great sections.  Also, 1,000s of examples in zip & PDF (fonts) files all demonstrated in this article!

  
3-  19 X 115 = 2185 Number 19 and BASMALA Miracle.  The total numerical value of Noble Verses 74:30-37 themselves, which are the heart of the Number 19 Miracle, has a stunning Miracle in it.  The value of these Noble Verses matches the multiplication of the BASMALA's number of letters (19 Letters) and their total numerical values (115): 19 X 115 = 2185.  The Basmala, which full text in Arabic means "In the Name of Allah The Most Beneficent, The Most Merciful" is the Key to the Glorious Quran.  It is recited first before reading the Holy Quran, and it is also obligatory upon every Muslim to start with the Basmala before starting any task.  Again, 1,000s of examples in zip & PDF (fonts) files all demonstrated in this article!

  
4-  Please also checkout the many hundreds (100s) of Great Numerical Miracles, and the many tens (10s) of other Great Scientific Miracles:

  
For example:

1-  The explosion of the Universe, Galaxies and Stars bring about Smoke.
  
"When the sky disintegrates, and turns rose colored like paint (وردة كالدهان)." (The Noble Quran, 55:37) [2] [3]
  

The Glorious Quran declares that the earth is spherical: [1]
  

Allah Almighty in the Glorious Quran said that earth is:        -  Spherical: "egg-shaped" [1].        -  Is rotating around itself.        -  Is moving in space in curvy orbits [2].        -  Is in constant motion.        -  Is suspended in space.        -  Is swimming in space.        -  Is traveling through the constantly expanding universe [3].        -  The sunsetless North Pole miracle in the Glorious Quran [4].  At the top of the North Pole, the sun never sets, and I showed the video for that, and also quoted the scientific sources for that. Also in the lands near by, it almost never sets either, and I quoted sources for that as well, and also showed pictures of the "polar night" skies on these lands.        -  The Glorious Quran also speaks about many earths [5] and not just earth.        -  The Glorious Quran predicts 11 planets in our solar system [6].

  
This is also all demonstrated in good details in the following video file and articles:
