How do Ants sense Food?
Sugar has a slight odor, particularly granulated beet sugar. While all species of ants can differentiate between a wide variety of odors, the smelling range differs from a few centimeters to meters. Desert ants can smell sugar from up to 3 meters.
the food sources that ants cannot smell from a distance they 'smell' it (contact chemoreception) by touching it. So in a way, all the food they detect, they detect it by smelling. So yes, ants smell (although contact chemoreception is more like taste) the sugar.
The ant colonies send scout ants to search for food in various directions, often up to a range of 100 to 200 meters.(Depends on the territorial boundary and time of the year). The scout marches steadily in less circuitous paths initially if it has memories of previous feeder locations. (Ants use visual landmarks, and a stereo-smell system to create an odor map and navigate) Periodically it will halt and look for olfactory cues. It will then take into a more circuitous random search. And as it nears the sugar and can smell it, its search ends.
The antennae of ants have hair-like sensilia that contain one or more sensory neurons. Most of the sensilia contain olfactory neurons. Each neuron sends a long nerve fiber through the antennal nerve that terminate in the antennal lobe of its brain. The axons from the olfactory neurons terminate in the lobe in globular structures called glomeruli. The antennal lobe of ants is particularly large and it has around 420-430 glomeruli. (A honey bee has 160). The more the glomeruli, the more variety of odors the ant can process. This provides for the acute smell sense of ants.
Once food is found, the scout collects a little sample of it and marches back to the colony finding the shortest route and leaving a pheromone trail behind. Once in the colony the other ants analyse the food the scout brought and take the trail set by the scout. As more ants get on the trail, they make the marking stronger so that other ants who went out on searches can smell the trail and join them.
This sugar detection process is not entirely intuitive and needs to be learnt. A leader scout takes a willing pupil with it to teach how to search for food. The pupil walks behind the teacher in a paired march called tandem running. The pair stops from time to time so that the pupil can commit the landmarks to its memory. When the pupil is done, it taps on its master's hind legs or abdomen two times and they start moving again. (If you see a pair stop like that, you can tap the hind legs of the master ant with a hair and it will keep moving. If the distance between the pupil and the master gets too large the master slows down while the pupil runs to catch up).

What is public domain books?
When a book has “entered the public domain”, its copyright has expired and the material now belongs to the general public. Not only does this mean that anybody can creatively reinvent that original work without paying a penny but also that this book is now free for anyone to read.

Why is a 'Red Cross' used as a medical symbol?
The sign of the Red Cross is associated with Red Cross Society, which is a voluntary organisation in the field of medical services. It was founded by Henry Dunant about 150 years ago. The sign is always found on hospitals, nursing homes, clinics, dispensary, ambulances, etc. The Blue Cross was introduced in the US but it is not as popular as the Red Cross, which is found worldwide. The reason crosses are used and associated with medical professions is mainly because of its use by the International Red Cross Society The Red Cross emblem was based on the design of the Swiss national flag. The red cross emblem can’t actually be used by doctors or anyone else, as it’s regarded as an internationally protected symbol.
The international Red Cross organization had won noble prize for its work for three times. Coming to the matter, red cross is named for offering unconditional help to the people in need. So, medical field, which also offers life saving services to the people adopted this symbol. That is the reason why hospitals and ambulances use red color plus symbol.

Before you argue with someone ask yourself " is this person mentally mature enough to grasp the concept of different perspectives?" if not there is no point to argue.

How do QR codes work?
QR codes are a technology that desperately wants our attention. They appear everywhere from supermarket shelves and magazines to hiking trails and tombstones.
QR (Quick Response) code is the trademark name for the two dimensional barcode system. It was originally invented in 1994 by Denso Wave, a Toyota subsidiary, as a way to track vehicles as they were assembled, and to scan components at high speeds. While Denso Wave does hold the patent on the technology, it has granted free licence on it, going so far as to publish the spec online, and allowing anyone to use it.
The conventional one dimensional barcodes used on virtually every consumer product are mechanically scanned. That is, they're read by physically bouncing a narrow beam of light onto the code, which can be interpreted using the pattern of light reflected off the white gaps between the lines.
A QR code works by encoding data in a certain way (a certain standard) so scanning software can interpret the results. For example, normal barcodes on products are considered 1D barcodes. The lines are different widths that correspond to numbers. Software interprets those line widths as numbers.
Same with the QR code; the location of each block is interpreted by the software and the combination of a bunch of blocks combine to represent certain characters. Combine the characters and you can get a URL for example.
If you add logic in the scanning software that opens a browser and goes to the link when the encoded data looks like a URL (with http://), you have added the functionality of translating printed material into digital material.
